pkglint -r --network --only "migrate"
As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

Changes:
4.13.0
- Security fixes
- CVE-2017-6949: Remove unchecked malloc() call in SRFI-4 constructors
when allocating in non-GC memory, resulting in potential 1-word
buffer overrun and/or segfault (thanks to Lemonboy).
- CVE-2017-9334: `length' no longer crashes on improper lists (fixes
#1375, thanks to "megane").
- CVE-2017-11343: The randomization factor of the symbol table was
set before the random seed was set, causing it to have a fixed value
on many platforms.
- Core Libraries
- Unit "posix": If file-lock, file-lock/blocking or file-unlock are
interrupted by a signal, we now retry (thanks to Joerg Wittenberger).
- char-ready? on string ports now also returns #t at EOF, as per R5RS;
in other words, it always returns #t (thanks to Moritz Heidkamp)
- Unit srfi-4: Fixed typo that broke SRFI-17 generalised set! syntax
on s8vectors (thanks to Kristian Lein-Mathisen).
- Large literals no longer crash with "invalid encoded numeric literal"
on mingw-64 (#1344, thanks to Lemonboy).
- Unit irregex: Fix bug that prevented multibyte UTF-8 character sets
from being matched correctly (Thanks to Lemonboy and Chunyang Xu).
- Runtime system:
- The profiler no longer uses malloc from a signal handler which may
cause deadlocks (#1414, thanks to Lemonboy).
- The scheduler no longer indirectly hangs on to the old thread
when switching to a new one, which caused excessive memory
consumption (#1367, thanks to "megane").
- C++ programs no longer fail with a symbol lookup error when
compiled with debugger support (-d3 or -debug-info).
- Syntax expander
- Renaming an identifier twice no longer results in an undo of the
rename (fixes#1362, thanks to "megane").
- Build system
- Fixed broken compilation on NetBSD, due to missing _NETBSD_SOURCE.
- Fixed compilation on DragonflyBSD due to no feature macro support
in its standard C library (thanks to Markus Pfeiffer).
- Compiler
- The scrutinizer no longer uses 'fixnum as the type for fixnums
that might not fit into a fixnum on 32-bit architectures.
- Foreign function interface
- Correctly calculate memory requirements of Scheme objects produced
from foreign types with "const" qualifiers, avoiding memory
corruption (#1424, thanks to Vasilij Schneidermann and Lemonboy)
- Do not read beyond temporary stack buffer, which could lead to
a crash when returning from a foreign callback (#1428).
4.12.0
- Security fixes
- CVE-2016-6830: Fix buffer overrun due to excessively long argument
or environment lists in process-execute and process-spawn (#1308).
This also removes unnecessary limitations on the length of
these lists (thanks to Vasilij Schneidermann).
- CVE-2016-6831: Fix memory leak in process-execute and
process-spawn. If, during argument and environment list
processing, a list item isn't a string, an exception is thrown,
in which case previously malloc()ed strings weren't freed.
- CVE-2016-9954: Irregex has been updated to 0.9.6, which fixes
an exponential explosion in compilation of nested "+" patterns.
- Compiler:
- define-constant now correctly keeps symbol values quoted.
- Warnings are now emitted when using vector-{ref,set!} or one
of take, drop, list-ref or list-tail with an out of range index
for vectors and proper lists of a definitely known length.
- The scrutinizer will no longer drop knowledge of the length of a
vector. It still drops types of its contents (which may be mutated).
- Fixed incorrect argvector restoration after GC in directly
recursive functions (#1317).
- "Direct" procedure invocations now also maintain debug info (#894).
- Syntax expander
- DSSSL lambda lists have improved hygiene, so they don't need
the chicken or scheme modules to be imported in full (#806).
- The let-optionals* macro no longer needs "quote", "car" and "cdr"
to be imported and bound to their default values (#806).
- Runtime system:
- C_locative_ref has been deprecated in favor of C_a_i_locative_ref,
which is faster because it is inlined (#1260, thanks to Kooda).
- The default error handler now truncates very long condition
messages (thanks to Lemonboy).
- Weak symbol GC (-:w) no longer drops random symbols (#1173).
- The number of arguments to procedures, both via "apply" and direct
invocation, are now limited only by the C stack size (#1098).
- "time" macro now shows peak memory usage (#1318, thanks to Kooda).
- Avoid crashes in ffi callbacks after GC (#1337, thanks to cosarara).
- Core libraries:
- Irregex has been updated to 0.9.5, which fixes matching of all "bow"
occurrances beyond the first with irregex-fold (upstream issue #14).
- Keywords are more consistently read/written, like symbols (#1332).
- SRFI-39: When jumping out of a parameterized dynamic extent,
"parameterize" now remember the actual values, so when jumping back
in, they are restored (fixes#1336, thanks to Joo ChurlSoo).
This was a regression caused by the fix for #1227.
- Tools:
- "chicken-install"
- When installing eggs in deploy mode with "-keep-installed", eggs
under the prefix won't unnecessarily be reinstalled (#1144).
- Added new option "-no-install-deps" which inhibits automatic
installation of dependencies, useful with "-prefix" (#1298).
This has been a pkglint warning for several years now, and pkglint can even
fix it automatically. And it did for this commit.
Only in lang/mercury, two passes of autofixing were necessary because there
were nested variables.

From Leonardo Taccari.
This release introduces several large changes, the one with the most
impact being a completely new calling convention for compiled CPS
procedures in C code. Instead of expecting "regular" C arguments,
the compiled C functions now accept a so-called "argvector" which
holds the arguments. This should greatly improve the portability of
CHICKEN programs, because it relies less on ill-specified parts of C.
It also removes the assembly code required for manyargs, so that the
limitation of 128 arguments for platforms without an "apply hack" has
finally been removed.
On the tooling front we've also added two new features: a statistical
profiler for analysing performance, and a graphical debugger called
"feathers", which allows you to inspect your Scheme programs over the
network. These have both been documented in the manual. The debugger
has its own chapter at https://wiki.call-cc.org/man/4/Debugging and the
profiler's new -:p runtime option is documented at
https://wiki.call-cc.org/man/4/Using%20the%20compiler#runtime-options
As usual, many bugs have been fixed with this release, including several
bugs that would cause programs to crash. All in all, this new release
should be much more robust and reliable.
For the complete list of changes since 4.10.0, see the NEWS file:
https://code.call-cc.org/releases/4.11.0/NEWS
This is mostly a bugfix release, containing quite a lot of accumulated
bug fixes but relatively few new features. Nevertheless, there are a
great many changes in this release since 4.9.0. It has three security
bugfixes: for CVE-2014-6310, CVE-2014-9651 and CVE-2015-4556.
Another important security-related cleanup/improvement is related to path
expansion: many file procedures in CHICKEN used to automatically and
implicitly convert paths containing tilde ("~") characters to $HOME,
and expand shell variables. This behaviour was deprecated in 4.9.0,
and has now been removed, in favor of the "pathname-expand" egg.
A few of the build variables have been renamed, so if you have a custom
build script, please review the NEWS file carefully.
Other notable changes:
* The performance of reading and writing SRFI-4 u8vectors has been
substantially improved.
* Various bugs in the functors implementation have been fixed, making
them better usable.
* chicken.h can once more be correctly compiled with a C++ compiler.
* The -r5rs-syntax flag has been fixed to enforce r5rs syntax.
For the full list of changes, see bundled NEWS or
http://code.call-cc.org/releases/4.10.0/NEWS-4.10.0
Tests now work without installing package first.
Changes since previous package:
4.9.0.1
- Runtime library
- C_MINOR_VERSION changed to 9; feature identifier chicken-4.8 => chicken-4.9

upon startup of csi, which could lead to untrusted code execution.
(thanks to Florian Zumbiehl)
- CVE-2013-2024: On *nix, the qs procedure now single-quotes everything
instead of relying on a blacklist of shell characters to be escaped.
On Windows, it properly duplicates double-quote characters. (thanks

- Removed the deprecated "c-runtime", "null-pointer?" and "pointer-offset"
procedures.
- The deprecated alias "mutate-procedure" for "mutate-procedure!" has

parameters (srfi-69).
- Platform support
- CHICKEN can now be built on AIX (contributed by Erik Falor)
- CHICKEN can now be built on GNU Hurd (contributed by Christian Kellermann)
- Basic support has been added for building Android and iOS binaries (see
the "README" file for caveats and pitfalls) (contributed by Felix Winkelmann
from bevuta IT GmbH)
- Added support for 64-bit Windows (consult the "README" file for more
information).
- Runtime system
- finalizers on constants are ignored in compiled code because compiled
constants are never GCed (before, the finalizer would be incorrectly
invoked after the first GC). (Reported by "Pluijzer")
- The call trace buffer is now also resizable at runtime via ##sys#resize-trace-buffer.
- C_zap_strings and ##sys#zap-strings (undocumented) have been deprecated.
- Special events in poll() are now handled, avoiding hangs in threaded apps.
- When invoking procedures with many rest arguments directly (not via APPLY),
raise an error when argument count limit was reached instead of crashing.
- When the maximum allowed heap size is reached, panic instead of crashing.
- The code generated for mutating data destructively is partially inlined
and thus slightly more efficient.
- Fixed incorrect code in the foreign argument conversion for
"unsigned-integer64" (#955). For unsigned-integer, integer64 and
unsigned-integer64, disallow floating-point numbers. Fix behavior
on 32-bit systems.
- On systems that provide sigprocmask(2), segmentation violations, illegal
instruction signals, bus errors and floating-point exceptions are now caught
and trigger normal error-processing (including a backtrace). The handling
of these so called "serious" signals can be disabled by passing the
"-:S" runtime option to executables.
- Reclamation of unused interned symbols (enabled with the "-:w" runtime option)
works much better now.
- Build system
- The tests can now be run without having to first install CHICKEN.
- Fixed a dependency problem that made it impossible to build the distribution
tarball on Windows with the mingw compiler.
- Increased the "binary compatibility version" to 7.
- Tools
- "csc"
- "-z origin" is now passed as a linker option on FreeBSD when
compiling for deployment (thanks to Jules Altfas & Vitaly Magerya)
- "-deploy" works now on FreeBSD (thanks to Jules Altfas and
Vitaly Magerya), OpenBSD and NetBSD (see README for NetBSD).
- added "-oi"/"-ot" options as alternatives to "-emit-inline-file"
and "-emit-type-file", respectively; "-n" has been deprecated.
- .c/.o files are no longer overwritten when they have the same basename
as a Scheme source file (i.e. "csc foo.scm foo.c -o foo" works now).
- "chicken-install"
- "-deploy" now correctly installs dependencies of
deployed eggs under the deployment directory instead of globally.
- Full URI syntax is now supported for proxy environment variables
(thanks to Michele La Monaca)
- "chicken-status"
- Added -eggs command line option to list installed eggs
- misc
- Removed the deprecated "-v" options (use "-version" instead) in various
core programs.
- The runtime linker path for compiled executables was not set correctly
on FreeBSD systems. This has now been fixed.
- Removed the deprecated "make" and "make/proc" facility from the
"setup-api" module; also removed the deprecated "required-extension-version"
and "required-chicken-version" procedures.
- Syntax
- Added the aliases "&optional" and "&rest" as alternatives to "#!optional"
and "#!rest" in type-declarations (suggested by Joerg Wittenberger).
- Vectors, SRFI-4 number vectors and blobs are now self-evaluating for
R7RS compatibility. Being literal constants, they are implicitly quoted.
- For R7RS compatibility, named character literals #\escape and #\null are
supported as aliases for #\esc and #\nul. WRITE will output R7RS names.
- The CASE form accepts => proc syntax, like COND (as specified by R7RS).
- letrec* was added for R7RS compatibility. Plain letrec no longer behaves
like letrec*.
- Compiler
- the "inline" declaration does not force inlining anymore as recursive
inlining could lead to non-termination of the compiler (thanks to
Andrei Barbu).
- Type-analysis ("scrutiny") is enabled by default now, unless
"-optimize-level 0" or "-no-usual-integrations" is given.
- The "-scrutinize" compiler option has been deprecated.
- A new lightweight flow-analysis pass ("lfa2") has been added.
Enable by passing the "-lfa2" option to the compiler.
- The deprecated options "-disable-warning", "-heap-growth", "-heap-shrinkage"
and "-heap-initial-size" have been removed.
- Removed the deprecated "constant" declaration.
- Removed the deprecated "-lambda-lift" and "-unboxing" compiler options.
- Removed the deprecated "-V" compiler option.
- Generated names for formal parameters of foreign functions are slightly
more informative.
- Unused references to variables that name intrinsics can be removed.
- In the flow-analysis pass, matching of combinations of "list"/"list-of" and
"or" types with has been made more reliable.
- Fixed various bugs in the type database.
- Syntax expander
- added "require-extension-for-syntax" and "use-for-syntax".
- Extended syntactic definitions are now available by default in all
evaluated code, particularly in code evaluated at runtime in compiled
applications.
- Removed the deprecated variant "(define-compiler-syntax (NAME . LLIST) BODY ...)"
of "define-compiler-syntax".
- C API
- Deprecated C_get_argument[_2] and C_get_environment_variable[_2] functions.
- Removed the deprecated "__byte_vector" type.

procedures accept extra arguments to control randomization for
testing/debugging.
- Added checks for embedded '\0' characters in strings passed to some
C functions on a lower level than Chicken's FFI.
- Build system

information gathered during flow analysis
- "-optimize-level 3" and higher now implies "-specialize"

in the generated C file
- the type-information obtained during flow-analysis ("scrutiny") is
now used for performing type-sensitive optimizations of calls to
most of the core-library procedures
- deprecated the "constant" declaration specifier
- "unboxing" optimization has been completely removed - the implementation
was unreliable and unmaintainable; the "-unboxing" compiler option will
still be accepted but will produce a warning

greatly reduces compile time for source code containing deeply nested
lexical bindings

- a number of bugs in the irregex regular expression engine have been
fixed; it has been updated to upstream release 0.8.3
- the "make" facility of the "setup-api" module has been deprecated,
please use the "make" extension when your egg requires this during
setup.

- The environment-variables "CHICKEN_C_INCLUDE_PATH" and
"CHICKEN_C_LIBRARY_PATH" can now be used to add default include-
and link-directories to C-compiler invocations

syntax definitions is deprecated - one should use "syntax-rules",
"er-macro-transformer" or "ir-macro-transformer" from now on
- Runtime system
- support for re-loading of compiled files has now been completely
removed
- the maximum length of strings is no longer limited to a 24-bit
number on 64-bit architectures but can be 56 bits.
- string-comparison handles embedded '\0' characters.
- numerical predicates handle infinity and NaN correctly.
- deprecated "[+-]nan", "[+-]inf" and other notations "accidentally"
accepted by Chicken due to the underlying C library's strtod() function,
standardizing on "[+-]nan.0" and "[+-]inf.0" from R6RS (and soon R7RS),
when displaying numbers only these forms are generated now.
- signals are queued to some extent and the interrupt handling has
been cleaned up somewhat
- the interpreter handles SIGINT directly - loading the "posix" unit
is not needed anymore to handle this feature
- changed default nursery size slightly and fixed a bug that caused
incorrect (too small) nursery sizes on 64-bit platforms
- deprecated the compiler option "-heap-initial-size", "-heap-growth"
and "-heap-shrinkage"
- the assembly-language stub routine for the implementation of "apply"
was broken for Sparc64 systems and has been disabled for this platform
- signal masks were accidentally reset upon GC for some platforms; use
sigsetjmp/siglongjmp on BSD, Linux, MacOS X and Haiku
- Type system
- added new type-specifiers "input-port", "output-port", "(list-of T)"
and "(vector-of T)"
- the type-specifiers "(vector T ...)" and "(list T ...)" represent
fixed size lists and vectors now
- added qualified types ("forall"), optionally with type constrains
- added the "define-type" special form and type-abbreviations
- added "compiler-typecase", a compile-time typematching form
- Module system
- Added "interfaces", which are named groups of exports
- Added "functors", which are parameterized modules
- Modules can now be aliased
- New syntax:
(define-interface NAME EXPORTS)
(functor (NAME ...) EXPORTS ...)
- Extended syntax of "module" for aliasing and functor-instantiation
- the "scheme" module has been integrated into the core library and
is not installed as a separate import library anymore
- added core module "r4rs" containing only bindings for R4RS identifiers
- added core module alias "r5rs" for "scheme" module
- added "module-environment" which returns an evaluation environment
for the bindings of a module
- fixed bugs related to using "export"/"reexport" in combination with
wildcard ("*") module export lists (thanks to "megane")
- Foreign function interface
- locatives are allowed as arguments declared "c-pointer"
Requested by Aleksej Lebedev in private mail.
Changes since 4.7.0:
4.7.0.6
The stability (-st) branch is now the official branch for point
releases, so the -st suffix has been retired.
- Security fixes
- on 64-bit machines the "random" procedure no longer truncates result
values (which caused very nonrandom results for very large values).
Note that random shouldn't be used for security-critical code.
- Core libraries
- tcp-connect now closes socket on connection timeout
[thanks to Jorg Wittenberger].
- Ensure srfi-13 string comparison returns a boolean, fix bugs in
xsubstring and string-xcopy!, and add a test suite.
- Fix off-by-one error in pending finalizer code which could lead to crash.
- Exceptions signalled by code that executes in finalizers will now
be caught and do not propagate upwards into arbitrary user code.
4.7.0.5-st
- Build system
- LLVM gcc and clang can now be used to compile the system. Previously,
building with LLVM produced binaries that would hang and use 100% CPU.

of conditionals (found by Paul Colby and Mario Domenench Goulart).
For example, this had printed "undefined" and now prints "good":
(define A #t)
(define B 'undefined)
(if A
(set! B 'good)
(set! B 'bad))
(print B)

- Build system
- On BSD, libchicken.so is linked with -lpthread, as this seems
to be required for linking libraries that require pthreads
- The C header-files are now installed in a subdirectory below
the "PRFIX/include" directory to allow installation of multiple
chickens with different PROGRAM_PREFIX/PROGRAM_SUFFIX settings
in the same prefix; to avoid conflicts with existing CHICKEN
headers, it is recommended to completely remove any old
installation before installing the new version
- the PROGRAM_PREFIX and PROGRAM_SUFFIX configuration settings
are applied to generated files and directories which allows
perform differently named installations into the same PREFIX
- increaded binary-compatibility version from 5 to 6, which
means installed extensions in an existing installations will
have to be re-installed

- "setup-api" unit
- `required-extension-version' and `required-chicken-version' have
been deprecated

- fixed incorrect lambda-list check in scrutinizer (thanks to
Alan Post)
- Kon Lovett reported numerous bugs in the type-database used
by the scrutinizer

now coined `notes' and are only shown in the interpreter
or when debug-mode is enabled or when scrutiny is enabled
when compiling

- the `-sx' option prefixes each output line with `;'
- slightly better expansion performance
- more documentation of the C API (thanks to Peter Bex)
- `module' supports a shorthand form that refers directly
to a file to be included as the module body
- added runtime option `-:G' to force GUI mode (on platforms
that distinguish between GUI and non-GUI applications)
- removed the unsafe runtime library (`libuchicken'), this
simplifies and speeds up the build and reduces the risk
of executables loading library units from different
variants of the runtime system
- removed the `-unsafe-libraries' option from `chicken'
and `csc'
- removed bootstrapping target and bootstrapping files from
development repository; to bootstrap the system, either
use a release or development-snapshot tarball or fetch
a statically linked precompiled `chicken' binary from
http://chicken.wiki.br/chicken-projects/bootstrap/
- Jim Ursetto provided some fixes for building universal
binaries on Mac OS X
- `csc' now compiles and links Windows resource (.rc) files
when given on the command line
- `chicken-install' and `chicken-uninstall' have an embedded
manifest that suppresses the elevation dialog on Windows
Vista and later when UAC is activated (Thanks to Thomas Chust)
- the `install' program is not used in the build on mingw
and mingw/MSYS platforms, since this is broken on older
mingw versions
- line-number-information is now properly handled (in the
few places where it is used) correctly for included files;
the source file is given in trace-output in addition to
the line number
- removed compiler warning for shared objects compiled in
unsafe mode
- unboxing is now only done in unsafe mode
- in unsafe mode, pointer-accessors from the `lolevel' unit
are now handled intrinsically by the compiler
- `chicken-install' accepts now relative pathnames for the
`-prefix' option
- `define-record-type' now optionally allows using SRFI-17
setters as record-field modifiers
- `integer?' returns `#f' for NaN and infinite numbers
- `csc' now has an `-no-elevation' option for embedding a
manifest that prevents the elevation dialog on Windows
Vista and later when IAC is activated
- the `,d' csi command displays qualified symbols properly
- symbols starting with the `#\#' character trigger an
error when encountered by the reader
- Unit posix: `glob->regexp' now always returns a regular
expression object or optionally an SRE
- Unit posix: `terminal-port?' and `terminal-size' have been
implemented for Windows, the latter always returns `0 0',
though (thanks to Jim Ursetto)
- Unit regex: `regexp' now accepts a regular expression
object as argument
- Unit regex: removed `glob?'
- fixed bug in `chicken-install'/`chicken-uninstall' and
`chicken-status' that prevented collapsed command-line
options to be handled correctly.
- disabled runpath-fix for deployed applications for netbsd
(but resurrected providing a runpath at all, thanks to
Peter Bex)
- Peter Bex provided documentation for the `C_closure' C API
function

New in Chicken 4.4.0:
- the system can now be built with llvm-gcc and/or "clang" (the
LLVM C compiler which doesn't use the GNU C frontend)
- added new option `-trunk' to `chicken-install', which forces
building and installing the development version of extensions
in combination with `-t local'
- added new option `-deploy' to `chicken-install', which builds
extension for use in "deployed" applications (see below)
- added option `-deploy' to `csc', the compiler driver. With this
option `csc' can build fully self-contained application bundles
and double-clickable Macintosh GUI apps; see the "Deployment"
manual chapter for more information
- the directory given to the `-prefix' option of `chicken-install'
may now be a relative pathname.
- removed GUI-specific runtime library (`libchicken-gui') from
Windows build - GUI- and non-GUI applications now use the same
runtime library
- special forms of the foreign-function interface have been replaced
with an internal form and syntax to allow renaming and shadowing of
these forms
- the new `-private-repository' option in `csc' compiles executables
with the extension-repository path set to the directory from which
the program was started
- `csc': deprecated the `-W' and `-windows' options, added `-gui' as
a platform-independent replacement
- `require-extension'/`use' accepts now import-specifications
- user-defined extension-specifiers and `set-extension-specifier!'
have been removed
- `delete-file[*]', `rename-file', `create-directory', `file-copy',
`file-move', `delete-directory' and `change-directory' return their
argument/destination filename on success
- added the missing procedure `condition-variable-name' to the
srfi-18 library unit (Thanks to Joerg Wittenberger)
- the `glob?' function from the `regex' unit has been deprecated
- added the procedure `scan-input-lines' to the `utils' library unit
- added new runtime option `-:g' which enables GC debugging output
- reclamation of unused symbols in "symbol-gc" mode (`-:w') now only
takes place for symbols with an empty property-list
- on Windows loading of code compiled with [non-]GUI runtime libraries
will fail and produce an error message when the loading executable
is linked with a different runtime system
- on Windows, GUI libraries were not correctly linked by `csc'
- unit posix: added setter for `file-modification-time'
- the banner shows the branchname of the build, unless it's "master"
- the `-no-install' option to `chicken-install' is ignored when
building/installing dependencies
- `chicken-uninstall' takes a glob instead of a regular expression as
argument
- the rename and compare functions for low-level macro-definitions
accept now arbitrary s-expressions and renames/compares them recursively
- `number->string' handles negative-numbers with bases different from 10
correctly (thanks to Peter Danenberg)
- removed deprecated `setup-install-flag' and `setup-verbose-flag' from
the `setup-api' module
- added new option `-repository' to `chicken-install' (Thanks to Christian
Kellermann)
- removed `chicken-setup' stub program
- fix to `csc' to use the correct library when fixing dynamic load paths
(Thanks to Derrell Piper)
- removed html documentation from distribution (the wiki manual will
now be installed)
- fixed bug in `reexport' which caused syntax not to be correctly
reexported
- previous assignments to a toplevel variable that are separated by
side effect free expressions are removed
- fixed windows version of `find-files' (thanks to Jim Ursetto)
- documentation for extensions is not installed automatically by
`chicken-install' anymore
- changed binary version from "4" to "5", because the new runtime
libraries are not binary-compatible with previous releases; this
means all eggs have to be reinstalled and existing programs be
recompiled!
- added unboxing pass to compiler which results in partially dramatical
performance improvements for unsafe floating-point-intensive code;
unboxing is enabled on optimization levels 4 and 5
- removed rest-argument-vector optimization as it could conflict
with inlining (thanks to Sven Hartrumpf)
- renamed `pointer-offset' to `pointer+' and deprecated `pointer-offset'
- toplevel assignments that have no other side-effects can be eliminated
if it can be shown that the value is not used (the compiler will
generate a warning in this case)
- removed deprecated `-quiet' option in `chicken' program
- removed deprecated `run-time-macros' declaration
- removed deprecated `-v2' and `-v3' options in `csc' program
- removed deprecated `list-of' function (it is exclusively available

especially for code compiled in unsafe mode
- calling `assert' with a single argument shows the tested expression
on failure
- various bugfixes and cleaning up
Patch provided by Peter Bex.

rules in some cases)
- it is now possible to pass a config-file to `make(1)' instead of specifying
all build-options as variables on the command-line (see README)
- removed compiler options for "benchmark-mode" and replaced them with a

definitions
- fix in optimizer that sometimes caused C functions for inlined
procedures to be emitted multiple times (Thanks to Joerg Wittenberger)

`feature?' instead)
- added topological-sort to data-structures unit; chicken-install
sorts dependencies before installing them
- "-optimize-level 2" enables inlining by default
- disable executable stack in assembly code modules (patch by
Zbigniew, reported by Marijn Schouten)
- csc now always exits with a status code of 1 on errors (patch by Zbigniew)

"setup-install-mode" and "setup-verbose-mode" in "setup-api" module,
the old names are still available but deprecated
- Posix unit:
added "socket?", "block-device?" and "character-device?", deprecated
redundant "stat-..." procedures
- Also in Posix unit: "canonical-path" has been deprecated, "normalize-pathname"
from the "files" unit provides now most of the functionality
- Added "directory-exists?"
- "(for-each (lambda ...) X)" is compiled as a loop
- The argument-count check for format-strings for "[sf]printf" with a constant
string argument is done at compile-time

developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
