Pkgsrc changes:
o Enable shared libraries for NetBSD, and deal with the resulting
fallout: tests which are written in C need to point their run-path
to the build version of the shared libraries.
o The default is shared libs with .so, except for on Darwin, where
shared libs are named differently. The Darwin part is untested.
(Korean) fonts, and add (commented) dependencies on them. Ok tnn@.
Bump PKGREVISION.
XXX uming/ukai (Chinese) are not in pkgsrc, anyone can package them, or suggest
replacements?

=============================
*Release date: 29-Sep-2009*
Core and Builtins
-----------------
- Issue #5329: Fix os.popen* regression from 2.5 with commands as a
sequence running through the shell. Patch by Jean-Paul Calderone
and Jani Hakala.
- Issue #6990: Fix threading.local subclasses leaving old state around
after a reference cycle GC which could be recycled by new locals.
- Issue #6922: Fix an infinite loop when trying to decode an invalid
UTF-32 stream with a non-raising error handler like "replace" or "ignore".

- Issue #6844: Do not emit DeprecationWarnings when accessing a "message"
attribute on exceptions that was set explicitly.
- Issue #6846: Fix bug where bytearray.pop() returns negative integers.
- Issue #6707: dir() on an uninitialized module caused a crash.
- Issue #6540: Fixed crash for bytearray.translate() with invalid parameters.
- Issue #6573: set.union() stopped processing inputs if an instance of self
occurred in the argument chain.
- Issue #6070: On posix platforms import no longer copies the execute bit
from the .py file to the .pyc file if it is set.
- Issue #4547: When debugging a very large function, it was not always
possible to update the lineno attribute of the current frame.
- Issue #4618: When unicode arguments are passed to print(), the default
separator and end should be unicode also.
- Issue #6119: Fixed a incorrect Py3k warning about order comparisons of
builtin functions and methods.
- Issue #5330: C functions called with keyword arguments were not reported by
the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.

field specifiers.
- Issue #5994: the marshal module now has docstrings.
- Issue #5981: Fix two minor inf/nan issues in float.fromhex: (1) inf
and nan strings with trailing whitespace were incorrectly rejected
and (2) the interpretation of fromhex('-nan') didn't match that of
float('-nan').
- Issue #5890: in subclasses of 'property' the __doc__ attribute was
shadowed by classtype's, even if it was None. property now
inserts the __doc__ into the subclass instance __dict__.
- Issue #5724: (See also issue #4575.) Fix Py_IS_INFINITY macro to
work correctly on x87 FPUs: it now forces its argument to double
before testing for infinity.

- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
PyUnicode_DecodeUTF8() once, remember the result and output it in a second
step. This avoids problems with counting UTF-8 bytes that ignores the effect
of using the replace error handler in PyUnicode_DecodeUTF8().

incorrectly on __exit__.
This builds, and will compile and run helloworld, but hasn't been
particularly extensively tested.
No version bump since no prior x86_64 packages should have been created.
Added scheme/unsafe/ops
Added print-syntax-width
Added file-or-directory-identity
Inside: embedding applications should call scheme_seal_parameters
after initializing parameter values (currently used by Planet)
ECL 9.10.2:
===========
* Bugs fixed:
- Fixed typo in src/c/unixint.d that affected single-threaded builds
- The GMP library did not build in OS X Snow Leopard in 64-bits mode.
- The package MP is needed also in single-threaded versions (for fake
mp:with-lock, which is used in CLX).
- In CLX, there were a couple of typos in the code related to locks and ECL.
These typos only revealed in multithreaded builds of the CLX library.
- In Linux there is a problem with handlers for SIGFPE being totally ignored
by the system. The problem seems to be solved by avoiding the use of
feenableexcept() and restricting to C99 exception tests. That is bad because
we can not reliably and cheaply detect underflow exceptions.
- Under OS X, --enable-rpath works again. It was broken for about a year
due to my misunderstanding of how -install_name works and the differences
between that and -rpath.
ECL 9.10.1:
===========
* Configuration flags:
- The option --enable-slow-config is now always on in Solaris and it does not
take more time than an ordinary build using --with-system-gmp=no
- A new compiler macro ECL_NO_LEGACY can be defined to remove all deprecated
macros and functions. Have a look at the end of src/h/external.h to see
what functions are deprecated on each release -- typically they are functions
that have been renamed with one of the prefixes, ecl_, cl_, si_, ext_ or _ecl.
- Under OS X, you can use the environment variable ABI to select between
32-bits (ABI=32) or 64-bits pointers (ABI=64).
* Bignums:
- When embedded, ECL may coexist with code that uses the GMP library in
different ways, and sometimes that code may use different memory allocation
routines. In order to solve this problem ECL introduces a new option,
ECL_OPT_SET_GMP_MEMORY_FUNCTIONS, which determines whether GMP will use the
Boehm-Weiser garbage collector to allocate memory or not.
- The previous change also implies that ECL must do all bignum computations
using GMP-allocated numbers that are then automatically freed. More
precisely, this is done using big_register[0-2]_get() and
big_register_normalize() everywhere and operating destructively on those
numbers. These functions have been made aware of the fact that GMP may
use other allocation routines and always call mpz_clear() to free memory.
- The internal functions dealing with bignums have been renamed with the usual
prefix "_ecl", and some of them have been turned into macros. Do not use
those functions if possible.
- Bignums are now allocated as a compact IMMUTABLE unit that combines the lisp
object and the data for the GMP integer itself. Since it can be now
allocated as an atomic (i.e. pointerless) region of memory, the garbage
collector has to work less for marking and collecting them.
- The function ecl_alloc_simple_vector() also creates arrays as a compact unit
with pointerfree memory whenever possible.
- The functions cl_alloc_simple_{base,extended}_string() now carry the prefix
ecl_ instead of cl_, and they are simple aliases for ecl_alloc_simple_vector.
- ECL now implements weak pointers. The interface is
(ext:make-weak-pointer value) => weak-pointer
(ext:weak-pointer-value weak-pointer) => value
and it defines a new built-in type, EXT:WEAK-POINTER
- When running in multithreaded mode, the streams for *terminal-io*,
*standard-input* and *standard-output* are created using non-locking
C pipes, instead of locking C streams. This is essential to allow background
threads gain control of the console.
* Native threads:
- ECL now implements WITHOUT-INTERRUPTS and WITH-INTERRUPTS similarly to SBCL.
It creates three local macros, ALLOW-WITH-INTERRUPTS and
WITH-LOCAL-INTERRUPTS, and an additional one WITH-RESTORED-INTERRUPTS,
which executes the forms with the value of interrupts of the forms that
surround WITHOUT-INTERRUPTS.
- Symbol SI:*INTERRUPT-DISABLE* changes name to SI:*INTERRUPTS-DISABLED*.
- New function MP:PROCESS-JOIN, waits for a thread to terminate (J.C.Beaudoin)
For this to work, threads are always created in a joinable state, and they
only detach themselves when exiting and no process is waiting.
- EXT:QUIT now has a different definition
(ext:quit &optional (exit-code 0) (kill-all-threads nil))
The first difference is that QUIT will execute all unwind-protect forms
that surrounds the form that caused the exit. The second one is that we
can explicitely kill all threads and wait for them to exit before exiting.
- Two new functions MP:PROCESS-SUSPEND and MP:PROCESS-RESUME allow suspending
and resuming a thread.
- The C function ecl_import_current_thread() now automatically registers the
thread with the garbage collector. You should use ecl_release_current_thread()
before the thread exits, for consistency.
- Due to the change in ecl_import_current_thread(), ECL now needs a slightly
more modern version of the Boehm-Weiser garbage collector. Hence, even if you
try to enforce --enable-boehm=system, you may find that ECL ignores the
pre-installed library in favor of the one shipped with it.
* Bugs fixed:
- WITH-LOCK might run into a race condition when the lock acquisition process
was interrupted.
- The following functions are now interrupt safe: MP:MAKE-LOCK.
- The use of GIVEUP-LOCK in WITH-LOCK is now protected against interrupts.
- Forms in toplevel EVAL-WHEN or PROGN statements did not have a proper value
of bytecodes.definition, causing the debugger to enter an infinite chain
of errors
- In Solaris 8 ECL failed because it did not find inttypes.h
- When signbit() is not available, ECL now looks for existence of copysign.
* Signals and environment:
- The toplevel now allows handling multiple processes in the same console.
Two new commands, :w and :s, allow reading the list of processes waiting for
grabbing the console and switching to that given process.
- ECL now has a signal handling thread running in the background. When
Ctrl-C or Ctrl-Break is pressed or the process gets a SIGINT signal, then
a separate thread is spawned for handling that event. This thread typically
enters the debugger, allowing either to continue or to interrupt specific
processes.
* Packages:
- The package hash tables are not destructively extended, but rather a new
hash table is created when we need more room. ecl_sethash() now returns
the pointer to the possibly reallocated hashtable.
- ECL now follows the SBCL model, by which there is a global lock for
destructive package operations (INTERN, EXPORT, etc), but not for
query only operations (FIND-SYMBOL, PACKAGE-USE-LIST), etc.
* Windows:
- The latest version of Visual Studio introduced a number of automatically
generated files (*.implib, *.manifest, *.expdef) which are not used at
all by ECL, but which were also not deleted, causing the temporary
directory to be filled with garbage.
- FASLs created by COMPILE and LOAD in the directory for temporary files are
now properly deleted before exiting ECL.
- ECL now embeds the manifest file in the generated executables and shared
libraries.
* Other errors:
- Extended strings (i.e. strings with characters that are not base-characters)
were not identified as valid documentation strings by the interpreter.
- Fix a bad reference to /bin/bash.
- Work around a non-portable argument to find.
This should address the bash issues reported in PR42092
lang/gcc44 leaves uncorrected reference to /bin/bash
