in select(); it supports no more than FD_SETSIZE descriptors.
- Core libraries
- Fixed EINTR handling in process-wait and when reading from file ports.
- Bugfix for irregex (#686). Note: although irregex.scm now says version
0.9.2, the version is actually 0.8.3 plus a few backported patches.
- Fixed problem in "make-pathname" that returned an absolute path if given
a relative one without a directory argument.
- On 64-bit systems the feature identifier "64bit" is registered.
- Compiler
- Fixed various bugs in the type database.
- Bugfixes and improvements in the scrutinizer.
- In the flow-analysis pass, type-matching of combinations of
"list"/"list-of" types has been made more reliable.
- Syntax expander
- Make macro-renamed defines in begin bodies (inside modules)
visible to later forms. (#944).
- Runtime system
- Fixed incorrect code in the foreign argument conversion for
"unsigned-integer64" (#955).
- Core tools
- The runtime linker path for compiled executables was not set correctly
on FreeBSD systems.
- Fix install-extension breakage when the second arg contains pairs (SRC DST).
- Build system
- Prevent rebuilding of buildversion.scm on every make(1) on Windows.
From Peter Bex via pkgsrc-wip.
Changes since 4.7.0.6:
- Security fixes
- improved hash table collision resistance and added randomization
to prevent malicious external causes of collisions. All SRFI-69
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
- version information has been moved into a separate unit to make the
build-version shown in the banner and accessible through library
procedures more accurate, this also speeds up the build on version-
changes (thanks to Jim Ursetto for contributing this)
- the build was made more reliable with respect to cross-compilation
and custom installation names
- the test-suite is now working on the mingw32 platform (with
a few tests disabled due to missing functionality)

into the core libraries and shown in the "csi" and "chicken"
version headers
- Compiler
- Fixed bug in handling of symbols in constant-definitions (thanks to Peter
Bex)
- Stricter check for value-part of constant definition (thanks to Kon Lovett)
- Fixed bug that caused argument-signatures of external definitions to be
incorrectly modified during optimization (thanks to Peter Bex)
- Failing constant-folding expressions now produce a compile-time warning
- Fixed various bugs in the internal type-database (thanks to Kon Lovett and
Peter Bex)
- added "-specialize" option and "specialize" declaration which enables
optimizations of uses of core library procedures based on type-
information gathered during flow analysis
- "-optimize-level 3" and higher now implies "-specialize"
- added option "-strict-types" and "-emit-type-file"
- progress-information is now only shown with "-debug p"; the "-verbose"
option only shows informational but noncritical messages
- added optimizations for some library procedures
- variable propagation for global variable accesses is now done in certain
situations
- the algorithmic complexity of the closure-conversion pass has been
reduced which speeds up compilation noticably for large files
- the alternative branch in a conditional is dropped when the condition
is known to be a non-boolean value (suggested by Joerg Wittenberger)
- implemented numerous fixes and improvements for flow analysis
- fixed a bug in the compiler that could cause some variable bindings
to be optimized away in certain situations involving inlining
- added an experimental optimization called "clustering" (enable
with the compiler option of the same name)
- the optimizations done by the compiler are now listed as a comment
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
- Peter Bex contributed an optimization to the analysis pass that
greatly reduces compile time for source code containing deeply nested
lexical bindings
- procedures that are known to have the value of a core library procedure
that is a "standard" or "extended binding" will be inlined
- enhanced line number tracking to get better error messages from
the scrutinizer.
- hygiene bugs related to compiler-syntax were fixed.

for the same type-conflict.
- the time/space-complexity of some algorithms used in the compiler
were reduced resulting in much better compile-times especially
for large source files.

- 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.

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

faster on Mac OS X (thanks to Jim Ursetto);
added new procedure `file-type'
- the `time' macro now shows the correct number of minor
garbage collections
- the immediate-object check inside the marking procedure
of the garbage collector has been manually inlined which
results in a significant GC speedup, depending on memory
load

disables predefined feature identifiers
- code compiled with interrupts disabled will not emit inline files
for global inlining since they may execute in a context where
interrupts are enabled
- the `setup.defaults' file that holds download sources for
`chicken-install' now allows aliases for locations
- CHICKEN systems build from cross-compilation now by default
transparently build and install extensions for both the host
and target parts of the cross-compilation setup; the options
`-host' and `-target' can now be used to selectively build
an extensions for the host- and the target system, respectively

- procedure-information shown by the printer for procedures is now
corrected for some library procedures that where missing the correct
information; `getter-with-setter' copies procedure-information objects
into the newly created accessor procedure, if available

the procedures are called with side-effect free arguments and the
result is not used (this can also by enabled for user procedures with
the `constant' declaration)

output instead of throwing an error to avoid endless recursion when
an error message is printed
- a feature identifier named `chicken-MAJOR.MINOR' is now defined
to simplify conditionalization of code on the CHICKEN version
- `getter-with-setter' copies the lambda-information (if available) from
the getter to the generated procedure
- `time' uses a somewhat more concise output format and outputs timing
information to stderr instead of stdout
- added a new chapter on cross-development to the manual
- added the `safe-globals' declaration specifier
- split up manual chapter `Modules and macros' into two chapters

or interpreter show the contextual form containing the expression,
or, if indicated by the context warns about missing imports
- simplified manual pages of all core tools - they now refer to
the output shown by invoking `<tool> -help'

evaluation order of the arguments and does a better job
at detecting non-list arguments (thanks to Jim Ursetto)
- `void' now takes arbitrary arguments and ignores them
- deprecated `noop' (from the `data-structures' unit) which
is now replaced by `void'
- the `time' macro now performs a major garbage collection
before executing the contained expressions and writes
the timings in a more compact format to the port given

- fixed bug in `chicken-install'/`chicken-uninstall' and
`chicken-status' that prevented collapsed command-line

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

- 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

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'

- libffi is not used anymore, handcoded assembler is used for x86, x86-64
and powerpc platforms
- TCP timeout handling
- added Lisp-style symbol property lists
- the "chicken-bug" program can now be used to create bug reports
- countless bugfixes and minor improvements
Based on patch provided by Alaric Snell-Pym in pkgsrc-users@.
Things changed since the last release (2.5):
- Many bugfixes
- Better support for Sun's C compiler
- Input-performance has been improved
- PCRE (Perl compatible regular expressions) by Philip Hazel is now
bundled with CHICKEN
- Static linking of extensions is now possible (when supported by
the egg)
- The interpreter warns about references to potentially unbound variables
in loaded code and expressions entered on the REPL
- The expansion process is traced during compilation and interpretation
to give (slightly) more usable syntactic context in error messages
- library:
* added `any?`, `bit-set?' and `on-exit'
- eval:
* new procedure `set-parameterized-read-syntax!'
- posix:
* SRFI-17 setters for `file-position`, `current-user-id',
`current-group-id', `process-group-id'; the respective setter-procedures
are still available but have been deprecated
* `file-stat' returns more information (including device info)
* added `process*'
- extras:
* added `read-string!'
- utils:
* `apropos' and `apropos-list' procedures
- srfi-4:
* added `read-u8vector', `read-u8vector!' and `write-u8vector'
- srfi-18:
* added `time->milliseconds' and `milliseconds->time'
- csi:
* `-ss SCRIPTNAME' option
- csc:
* accepts options given in the environment variable `CSC_OPTIONS'
* new options `-static-extensions' and `-host'
- chicken/csc:
* new option `-keep-shadowed-macros'
- chicken-setup:
* accepts options given in the environment variable `CHICKEN_SETUP_OPTIONS'
* allows retrieval and installation of eggs from subversion a repository
and the local filesystem
* new options `-tree FILENAME', `-svn', `-local', `-revision' and
`-destdir PATHNAME'
* added helper procedures `required-chicken-version' and
`required-extension-version'
- Lots of improvements in the CMake build
Based on patch provided by Peter Schuller in PR 35339.
Changes:
- Bugfixes
- CHICKEN can now be built using CMake <http://www.cmake.org>, in fact CMake
is required to built CHICKEN from sources on Windows with the Microsoft
tools
- the whole build process has been cleaned up and simplified
- the "easyffi" and "tinyclos" library units have been removed from the base
system and are now available as separate extensions
- the deprecated "set-dispatch-read-syntax!" has been removed
- Will Farr cleaned up the behaviour of number-type specific numeric operations
("fx..."/"fp...") with respect to safe/unsafe mode
- added "(finite? NUMBER)"
- the "$" macro moved into its own separate extension
- the values of "software-type", "software-version", "machine-type" and "machine
-byte-order"
are now registered as features and can be tested using "cond-expand" or "#+"
- all tools now support the "-release" option
- chicken-setup: added "-test" option
In Changelog:
- Many bugfixes
- chicken-config was removed, "csc" providing the same functionality
- option -objc generates files in Objective-C mode
- options '-framework', '-rpath'...

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.
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".
Provided in PR pkg/26832 by Peter dot Bex at student dot kun dot nl
with minor additions (info file handling and resource limit specification
so test target runs on my test platforms).
Many changes since last packaged version, too many to list here.

- `csc' added `-s' option to linker, when linking with optimization (won't
work when building shared object)
- fixed countless typos in manual.tex [Thanks to Bruce Mitchener]
- `csc' uses `-bundle' instead of `-shared' under Mac OS X
- runtime.c: dload_2 prefixes dlsym'd name with "_"
- posix.scm: under Mac OS X, `environ' is not used (and `current-environment'
always returns '())
- removed `C_collectibles' and added `C_gc_protect()' and `C_gc_unprotect()'
- fixed compiler bug that caused repeated explicit rest-argument list consing
[Thanks to Sven Hartrumpf]
- added `string-compare3[-ci]'
- reduced C_STACK_RESERVE to 4096; the previous setting could overflow the
stack-check on machines with a stack in very high memory
