2012-10-24 Stephane Clairet <Stephane dot Clairet at 4d dot com>
* pthread_key_delete.c: Bug fix - move keylock release to after the
while loop. (This bug first was introduced at release 2.9.1)
2012-10-16 Ross Johnson <ross dot johnson at homemail dot com dot au>
* Makefile: Remove SDK environment setting; now needs to be done
explicitly before running any nmake.
* GNUmakefile: Move per command-line ARCH setting to TESTS_ENV.
2012-10-04 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread_tryjoin_np.c: New API
* pthread.c (pthread_try_join_np): Added.
* common.mk (pthread_tryjoin_np): Added.
* pthread.h (pthread_tryjoin_np): Added.
* NEWS: Updated.
* README: Updated.
* ANNOUNCE: Updated.
2012-10-02 Ross Johnson <ross dot johnson at homemail dot com dot au>
* sched.h (cpu_set_t): Redefined.
* implement.h (_sched_cpu_set_vector_): Created as the private equivalent
of cpu_set.
(pthread_thread_t_.cpuset): Type change.
* sched_setaffinity.c: Reflect changes to cpu_set_t and _sched_cpu_set_vector_.
* pthread_setaffinity.c: Likewise.
* create.c: Likewise.
* pthread_self.c: Likewise.
* ptw32_new.c: Likewise.
2012-09-28 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread.c: pulls all individual source modules into a single
translation unit.
* common.mk: Remove everything related to the non-inlined dll targets.
This removes all the intermediate .c files that #include other .c files
except for pthread.c.
* Makefile: Remove and rename targets; remove or edit variables. All
of this is to remove the intermediate translation unit aggregation
source files.
* GNUmakefile: Likewise.
* attr.c: Removed.
* barrier.c: Removed.
* cancel.c: Removed.
* condvar.c: Removed.
* exit.c: Removed.
* fork.c: Removed.
* misc.c: Removed.
* mutex.c: Removed.
* nonportable.c: Removed.
* private.c: Removed.
* rwlock.c: Removed.
* sched.c: Removed.
* spin.c: Removed.
* sync.c: Removed.
* tsd.c: Removed.
2012-09-28 Ross Johnson <ross dot johnson at homemail dot com dot au>
* Makefile: expand on rudimentary install target; add DEST_LIB_NAME
variable defaulting to "pthread.lib".
* GNUmakefile: Add install target similar to Makefile with DEST_LIB_NAME
defaulting to "libpthread.a".
2012-09-28 Daniel Richard. G <danielg at teragram dot com>
* all: #include<config.h>; renamed HAVE_PTW32_CONFIG_H define in
build files to HAVE_CONFIG_H since we no longer need a
uniquely-named symbol for this.
* Bmakefile: Removed _WIN32_WINNT assignment from build files since
this is now handled in source.
* Wmakefile: Likewise.
* Makefile: Added mkdir invocations to "install" target.
* common.mk: Elaborated the pthread.$(OBJEXT) dependency list.
* pthread.h: Removed the #include"config.h" bit.
2012-09-23 Ross Johnson <ross dot johnson at homemail dot com dot au>
* GNUmakefile: Modify "all-tests" to use new targets in tests
GNUmakefile.
* Makefile: Similarly.
2012-09-22 Daniel Richard. G <danielg at teragram dot com>
* GNUmakefile: Reordered the command lines in the "help" target
to match the ordering of the targets in the makefile, which IMO
is nicer to the eye; tweaked some of the parentheticals for better
clarity; delete *.manifest files, in case the user just finished
doing an MSVC build.
* Makefile: Use *.static_stamp for the static targets instead of
*.static; added a note re VC++6 and /EHs vs. /EHa; reordered the
targets, and added a number of new ones (e.g. VSE-small-static);
added a note recommending *-inlined and *-small-static to make
things a little easier for users bewildered by the large number of
targets; reworked the all-tests[-cflags] targets so that (1) more
useful targets are built first (the small-static targets make it
easier to track down compilation errors), (2) *-debug build and
test targets can be used, (3) less-useful build/test permutations
are enabled only if EXHAUSTIVE and/or MORE_EXHAUSTIVE is defined,
and (4) /MDd and /MTd are covered too; "nmake all-tests-cflags
EXHAUSTIVE=1 MORE_EXHAUSTIVE=1" takes a few hours to run; moved
some of the VCE targets up, since the pattern in the file was
already to list VCE targets first, then VSE, then VC; actually
touch the stamp file in the stamp targets.
* README.NONPORTABLE: It's "DllMain", not "dllMain".
* common.mk: Start of an attempt to define dependencies for
pthread.$(OBJEXT).
* implement.h: Generalized PTW32_BROKEN_ERRNO into
PTW32_USES_SEPARATE_CRT; don't do the autostatic-anchoring thing
if we're not building the library!
* pthread.h: Moved the PTW32_CDECL bit into sched.h. pthread.h
already #includes sched.h, so the latter is a good place to put
definitions that need to be shared in common; severely simplified
the errno declaration for Open Watcom, made it applicable only to
Open Watcom, and made the comment less ambiguous; updated the long
comment describing PTW32_BROK^WPTW32_USES_SEPARATE_CRT; added
(conditional) declaration of pthread_win32_set_terminate_np(), as
well as ptw32_terminate_handler (so that eh.h doesn't have to get
involved).
* pthread_cond_wait.c: Missed a couple of errno conversions.
* pthread_mutex_consistent.c: Visual Studio (either 2010 or 2008
Express, don't recall now) actually errored out due to charset
issues in this file, so I've replaced non-ASCII characters with
ASCII approximations.
* ptw32_threadStart.c: Big rewrite of ptw32_threadStart().
Everything passes with this, except for GCE (and I can't figure
out why).
* sched.h: Moved the PTW32_CDECL section here (and made it
idempotent); need to #include <stdlib.h> for size_t (one of the test
programs #includes sched.h as the very first thing); moved the
DWORD_PTR definition up, since it groups better with the pid_t
definition; also need ULONG_PTR, don't need PDWORD_PTR; can't use
PTW32_CONFIG_MSVC6, because if you only #include sched.h you
don't get that bit in pthread.h; use a cpp symbol
(PTW32_HAVE_DWORD_PTR) to inhibit defining *_PTR if needed. Note
that this isn't #defined inside the conditional, because there are
no other instances of these typedefs that need to be disabled, and
sched.h itself is already protected against multiple inclusion;
DWORD_PTR can't be size_t, because (on MSVC6) the former is "unsigned
long" and the latter is "unsigned int" and C++ doesn't see them as
interchangeable; minor edit to the comment... I don't like saying
"VC++" without the "Microsoft" qualifier; use PTW32_CDECL instead of
a literal __cdecl (this was why I moved the PTW32_CDECL bit into this
file).
* semaphore.h: Put in another idempotentized PTW32_CDECL bit here;
use PTW32_CDECL instead of __cdecl, and fixed indentation of function
formal parameters.
2012-09-21 Ross Johnson <ross dot johnson at homemail dot com dot au>
* create.c: Major changes to incorporate CPU affinity inheritance.
* pthread_self.c: Likewise.
* ptw32_new.c (cpuset): Initialise new pthread_thread_t element.

in tests/once3.c which was causing it to hang.
2012-09-03 Ross Johnson <ross dot johnson at homemail dot com dot au>
* Makefile: Remove descriptive info from help target, just list the
available targets. Output tends to be poorly formatted and cluttered
otherwise.

return statement.
2012-08-31 Daniel Richard. G <danielg at teragram dot com>
* implement.h (INLINE): only define if building the inlined make targets. G++
complained about undefined reference to ptw32_robust_mutex_remove() because it
appears in separate compilation units for "make GCE".

2011-07-06 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread_cond_wait.c (pragma inline_depth): this is almost redundant
now nevertheless fixed thei controlling MSC_VER from "< 800" to
"< 1400" (i.e. any prior to VC++ 8.0).
* pthread_once.ci (pragma inline_depth): Likewise.
* pthread_rwlock_timedwrlock.ci (pragma inline_depth): Likewise.
* pthread_rwlock_wrlock.ci (pragma inline_depth): Likewise.

2011-07-05 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread_win32_attach_detach_np.c: Use strncat_s if available
to removei a compile warning; MingW supports this routine but we
continue to use strncat anyway there because it is secure if
given the correct parameters; fix strncat param 3 to avoid
buffer overrun exploitation potential.
2011-07-03 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread_spin_unlock.c (EPERM): Return success if unlocking a lock
that is not locked, because single CPU machines wrap a
PTHREAD_MUTEX_NORMAL mutex, which returns success in this case.
* pthread_win32_attach_detach_np.c (QUSEREX.DLL): Load from an
absolute path only which must be the Windows System folder.
2011-07-03 Daniel Richard G. <skunk at iskunk dot org>

* implement.h: Interlocked call and argument casting macro fixes
to support older and newer build environments.
2011-07-01 Ross Johnson <ross dot johnson at homemail dot com dot au>
* *.[ch] (PTW32_INTERLOCKED_*): Redo 23 and 64 bit versions of these
macros and re-apply in code to undo the incorrect changes from
2011-06-29; remove some size_t casts which should not be required
and may be problematic.a
There are now two sets of macros:
PTW32_INTERLOCKED_*_LONG which work only on 32 bit integer variables;
PTW32_INTERLOCKED_*_SIZE which work on size_t integer variables, i.e.
LONG for 32 bit systems and LONGLONG for 64 bit systems.

pointer cast for 64 bit compatibility (missed yesterday); remove
the superfluous static cleanup routine and call the release routine
directly if popped.

_ftime64_s() is only available in MSVC 2005 or later;
_ftime64() is available in MinGW or MSVC 2002 or later;
_ftime() is always available.
* pthread.h (long long): Not defined in older MSVC 6.
* implement.h (long long): Likewise.
* pthread_getunique_np.c (long long): Likewise.
2011-06-29 Ross Johnson <ross dot johnson at homemail dot com dot au>
* *.[ch] (PTW32_INTERLOCKED_*): These macros should now work for
both 32 and 64 bit builds. The MingW versions are all inlined asm
while the MSVC versions expand to their Interlocked* or Interlocked*64
counterparts appropriately. The argument type have also been changed
to cast to the appropriate value or pointer size for the architecture.
2011-05-29 Ross Johnson <ross dot johnson at homemail dot com dot au>
* *.[ch] (#ifdef): Extended cleanup to whole project.
2011-05-29 Daniel Richard G. <skunk at iskunk dot org>

* GNUmakefile (GCE-inlined-debug, DOPT): Fixed.
2011-04-31 Ross Johnson <ross.johnson at homemail.com.au>
* (robust mutexes): Added this API. The API is not
mandatory for implementations that don't support PROCESS_SHARED
mutexes, nevertheless it was considered useful both functionally
and for source-level compatibility.
2011-03-26 Ross Johnson <ross.johnson at homemail.com.au>
* pthread_getunique_np.c: New non-POSIX interface for compatibility
with some other implementations; returns a 64 bit sequence number
that is unique to each thread in the process.
* pthread.h (pthread_getunique_np): Added.
* global.c: Add global sequence counter for above.
* implement.h: Likewise.
2011-03-26 Ross Johnson <ross at homemail dot com dot au>

clean build via x86_64-w64-mingw32 cross toolchain on Linux i686
targeting x86_64 win64.
* ptw32_threadStart.c (ptw32_threadStart): Routine no longer attempts
to pass [unexpected C++] exceptions out of scope but ends the thread
normally setting EINTR as the exit status.
* ptw32_throw.c: Fix C++ exception throwing warnings; ignore
informational warning.
* implement.h: Likewise with the corresponding header definition.
2011-03-04 Ross Johnson <ross.johnson at homemail.com.au>
* implement.h (PTW32_INTERLOCKED_*): Mingw32 does not provide
the __sync_* intrinsics so implemented them here as macro
assembler routines. MSVS Interlocked* are emmitted as intrinsics
wherever possible, so we want mingw to match it; Extended to
include all interlocked routines used by the library; implemented
x86_64 versions also.
* ptw32_InterlockedCompareExchange.c: No code remaining here.
* ptw32_MCS_lock.c: Converted interlocked calls to use new macros.
* pthread_barrier_wait.c: Likewise.
* pthread_once.c: Likewise.
* ptw32_MCS_lock.c (ptw32_mcs_node_substitute): Name changed to
ptw32_mcs_node_transfer.
2011-02-28 Ross Johnson <ross.johnson at homemail.com.au>
* ptw32_relmillisecs.c: If possible, use _ftime64_s or _ftime64
before resorting to _ftime.
2011-02-27 Ross Johnson <ross.johnson at homemail.com.au>
* sched_setscheduler.c: Ensure the handle is closed after use.

* pthread_exit.c: Likewise.
* pthread_spin_destroy.c: Likewise.
* pthread_timechange_handler_np.c: Likewise.
* ptw32_MCS_lock.c: Likewise; some of these changes may
not be compatible with pre Windows 2000 systems; reverse the order of
the includes.
* ptw32_threadStart.c: Likewise.
* ptw32_throw.c: Likewise.
2011-02-13 Ross Johnson <ross.johnson at homemail.com.au>
* pthread_self: Add comment re returning 'nil' value to
indicate failure only to win32 threads that call us.
* pthread_attr_setstackaddr: Fix comments; note this
function and it's compliment are now removed from SUSv4.
2011-02-12 Ross Johnson <ross.johnson at homemail.com.au>
README.NONPORTABLE: Record a description of an obvious
method for nulling/comparing/hashing pthread_t using a
union; plus and investigation of a change of type for
pthread_t (to a union) to neutralise any padding bits and
bytes if they occur in pthread_t (the current pthread_t struct
does not contain padding AFAIK, but porting the library to a
future architecture may introduce them). Padding affects
byte-by-byte copies and compare operations.
2010-11-16 Ross Johnson <ross.johnson at homemail.com.au>
* ChangeLog: Add this entry ;-)
Restore entries from 2007 through 2009 that went missing
at the last update.
2010-06-19 Ross Johnson <ross.johnson at homemail.com.au>
* ptw32_MCS_lock.c (ptw32_mcs_node_substitute): Fix variable

2010-01-26 Ross Johnson <ross.johnson at homemail.com.au>
* ptw32_MCS_lock.c (ptw32_mcs_node_substitute): New routine
to allow relocating the lock owners thread-local node to somewhere
else, e.g. to global space so that another thread can release the
lock. Used in pthread_barrier_wait.
(ptw32_mcs_lock_try_acquire): New routine.
* pthread_barrier_init: Only one semaphore is used now.
* pthread_barrier_wait: Added an MCS guard lock with the last thread
to leave the barrier releasing the lock. This removes a deadlock bug
observed when there are greater than barrier-count threads
attempting to cross.
* pthread_barrier_destroy: Added an MCS guard lock.
2009-03-03 Stephan O'Farrill <stephan dot ofarrill at gmail dot com>

2008-06-06 Robert Kindred <RKindred at SwRI dot edu>
* ptw32_throw.c (ptw32_throw): Remove possible reference to NULL
pointer. (At the same time made the switch block conditionally
included only if exitCode is needed - RPJ.)
* pthread_testcancel.c (pthread_testcancel): Remove duplicate and
misplaced pthread_mutex_unlock().
2008-02-21 Sebastian Gottschalk <seppig_relay at gmx dot de>

Remove potential and superfluous null pointer assignment.
2007-11-22 Ivan Pizhenko <ivanp4 at ua dot fm>
* pthread.h (gmtime_r): gmtime returns 0 if tm represents a time
prior to 1/1/1970. Notice this to prevent raising an exception.

_errno() is used, e.g. by WinCE.
2007-01-06 Ross Johnson <ross.johnson at homemail dot com dot au>
* ptw32_semwait.c: Add check for invalid sem_t after acquiring the

2007-01-06 Romano Paolo Tenca <rotenca at telvia dot it>
* pthread_cond_destroy.c: Replace sem_wait() with non-cancelable
ptw32_semwait() since pthread_cond_destroy() is not a cancellation
point.
* implement.h (ptw32_spinlock_check_need_init): Add prototype.
* ptw32_MCS_lock.c: Reverse order of includes.
2007-01-06 Eric Berge <eric dot berge at quantum dot com>
* pthread_cond_destroy.c: Add LeaveCriticalSection before returning
after errors.
2007-01-04 Ross Johnson <ross.johnson at homemail dot com dot au>
* ptw32_InterlockedCompareExchange.c: Conditionally skip for
Win64 as not required.
* pthread_win32_attach_detach_np.c (pthread_win32_process_attach_np):
Test for InterlockedCompareExchange is not required for Win64.
* context.h: New file. Included by pthread_cancel.h and any tests
that need it (e.g. context1.c).
* pthread_cancel.c: Architecture-dependent context macros moved
to context.h.
2007-01-04 Kip Streithorst <KSTREITH at ball dot com>
* implement.h (PTW32_INTERLOCKED_COMPARE_EXCHANGE): Add Win64
support.
2006-12-20 Ross Johnson <ross.johnson at homemail.com.au>
* sem_destroy.c: Fix the race involving invalidation of the sema;
fix incorrect return of EBUSY resulting from the mutex trylock
on the private mutex guard.
* sem_wait.c: Add check for invalid sem_t after acquiring the
sem_t state guard mutex and before affecting changes to sema state.
* sem_trywait.c: Likewise.
* sem_timedwait.c: Likewise.
* sem_getvalue.c: Likewise.
* sem_post.c: Similar.
* sem_post_multiple.c: Likewise.
* sem_init.c: Set max Win32 semaphore count to SEM_VALUE_MAX (was
_POSIX_SEM_VALUE_MAX, which is a lower value - the minimum).
* pthread_win32_attach_detach_np.c (pthread_win32_process_attach_np):
Load COREDLL.DLL under WINCE to check existence of
InterlockedCompareExchange() routine. This used to be done to test
for TryEnterCriticalSection() but was removed when this was no
longer needed.
2006-01-25 Prashant Thakre <prashant.thakre at gmail.com>
* pthread_cancel.c: Added _M_IA64 register context support.
2005-05-13 Ross Johnson <ross at callisto.canberra.edu.au>
* pthread_kill.c (pthread_kill): Remove check for Win32 thread
priority (to confirm HANDLE validity). Useless since thread HANDLEs
a not recycle-unique.
2005-05-30 Vladimir Kliatchko <vladimir at kliatchko.com>
* pthread_once.c: Re-implement using an MCS queue-based lock. The form
of pthread_once is as proposed by Alexander Terekhov (see entry of
2005-03-13). The MCS lock implementation does not require a unique
'name' to identify the lock between threads. Attempts to get the Event
or Semaphore based versions of pthread_once to a satisfactory level
of robustness have thus far failed. The last problem (avoiding races
involving non recycle-unique Win32 HANDLEs) was giving everyone
grey hair trying to solve it.
* ptw32_MCS_lock.c: New MCS queue-based lock implementation. These
locks are efficient: they have very low overhead in the uncontended case;
are efficient in contention and minimise cache-coherence updates in
managing the user level FIFO queue; do not require an ABI change in the
library.
2005-05-27 Alexander Gottwald <alexander.gottwald at s1999.tu-chemnitz.de>
* pthread.h: Some things, like HANDLE, were only defined if
PTW32_LEVEL was >= 3. They should always be defined.
2005-05-25 Vladimir Kliatchko <vladimir at kliatchko.com>
* pthread_once.c: Eliminate all priority operations and other
complexity by replacing the event with a semaphore. The advantage
of the change is the ability to release just one waiter if the
init_routine thread is cancelled yet still release all waiters when
done. Simplify once_control state checks to improve efficiency
further.
2005-05-24 Mikael Magnusson <mikaelmagnusson at glocalnet.net>
* GNUmakefile: Patched to allow cross-compile with mingw32 on Linux.
It uses macros instead of referencing dlltool, gcc and g++ directly;
added a call to ranlib. For example the GC static library can be
built with:
make CC=i586-mingw32msvc-gcc RC=i586-mingw32msvc-windres \

* pthread_win32_attach_detach_np.c (pthread_win32_thread_detach_np):
Move on-exit-only stuff from ptw32_threadDestroy() to here.
* ptw32_threadDestroy.c: It's purpose is now only to reclaim thread
resources for detached threads, or via pthread_join() or
pthread_detach() on joinable threads.
* ptw32_threadStart.c: Calling user destruct routines has moved to
pthread_win32_thread_detach_np(); call pthread_win32_thread_detach_np()
directly if statically linking, otherwise do so via dllMain; store
thread return value in thread struct for all cases, including
cancellation and exception exits; thread abnormal exits go via
pthread_win32_thread_detach_np.
* pthread_join.c (pthread_join): Don't try to get return code from
Win32 thread - always get it from he thread struct.
* pthread_detach.c (pthread_detach): reduce extent of the thread
existence check since we now don't care if the Win32 thread HANDLE has
been closed; reclaim thread resources if the thread has exited already.
* ptw32_throw.c (ptw32_throw): For Win32 threads that are not implicit,
only Call thread cleanup if statically linking, otherwise leave it to
dllMain.
* sem_post.c (_POSIX_SEM_VALUE_MAX): Change to SEM_VALUE_MAX.
* sem_post_multiple.c: Likewise.
* sem_init.c: Likewise.
2005-05-10 Ross Johnson <ross at callisto.canberra.edu.au>
* pthread_join.c (pthread_join): Add missing check for thread ID
reference count in thread existence test; reduce extent of the
existence test since we don't care if the Win32 thread HANDLE has
been closed.
2005-05-09 Ross Johnson <ross at callisto.canberra.edu.au>
* ptw32_callUserDestroyRoutines.c: Run destructor process (i.e.
loop over all keys calling destructors) up to
PTHREAD_DESTRUCTOR_ITERATIONS times if TSD value isn't NULL yet;
modify assoc management.
* pthread_key_delete.c: Modify assoc management.
* ptw32_tkAssocDestroy.c: Fix error in assoc removal from chains.
* pthread.h
(_POSIX_THREAD_DESTRUCTOR_ITERATIONS): Define to value specified by
POSIX.
(_POSIX_THREAD_KEYS_MAX): Define to value specified by POSIX.
(PTHREAD_KEYS_MAX): Redefine [upward] to minimum required by POSIX.
(SEM_NSEMS_MAX): Define to implementation value.
(SEM_VALUE_MAX): Define to implementation value.
(_POSIX_SEM_NSEMS_MAX): Redefine to value specified by POSIX.
(_POSIX_SEM_VALUE_MAX): Redefine to value specified by POSIX.
2005-05-06 Ross Johnson <ross at callisto.canberra.edu.au>
* signal.c (sigwait): Add a cancellation point to this otherwise
no-op.
* sem_init.c (sem_init): Check for and return ERANGE error.
* sem_post.c (sem_post): Likewise.
* sem_post_multiple.c (sem_post_multiple): Likewise.
* manual (directory): Added; see ChangeLog inside.

* implement.h (struct pthread_key_t_): Change threadsLock to keyLock
so as not to be confused with the per thread lock 'threadlock';
change all references to it.
* implement.h (struct ThreadKeyAssoc): Remove lock; add prevKey
and prevThread pointers; re-implemented all routines that use this
struct. The effect of this is to save one handle per association,
which could potentially equal the number of keys multiplied by the
number of threads, accumulating over time - and to free the
association memory as soon as it is no longer referenced by either
the key or the thread. Previously, the handle and memory were
released only after BOTH key and thread no longer referenced the
association. That is, often no association resources were released
until the process itself exited. In addition, at least one race
condition has been removed - where two threads could attempt to
release the association resources simultaneously - one via
ptw32_callUserDestroyRoutines and the other via
pthread_key_delete.
- thanks to Richard Hughes at Aculab for discovering the problem.

* sem_wait.c (ptw32_sem_wait_cleanup): after cancellation re-attempt
to acquire the semaphore to avoid a race with a late sem_post.
* sem_timedwait.c: Modify comments.
2005-04-25 Ross Johnson <ross at callisto.canberra.edu.au>
* ptw32_relmillisecs.c: New module; converts future abstime to
milliseconds relative to 'now'.
* pthread_mutex_timedlock.c: Use new ptw32_relmillisecs routine in
place of internal code; remove the NEED_SEM code - this routine is now
implemented for builds that define NEED_SEM (WinCE etc)
* sem_timedwait.c: Likewise; after timeout or cancellation,
re-attempt to acquire the semaphore in case one has been posted since
the timeout/cancel occurred. Thanks to Stefan Mueller.
* Makefile: Add ptw32_relmillisecs.c module; remove
ptw32_{in,de}crease_semaphore.c modules.
* GNUmakefile: Likewise.
* Bmakefile: Likewise.
* sem_init.c: Re-write the NEED_SEM code to be consistent with the
non-NEED_SEM code, but retaining use of an event in place of the w32 sema
for w32 systems that don't include semaphores (WinCE);
the NEED_SEM versions of semaphores has been broken for a long time but is
now fixed and supports all of the same routines as the non-NEED_SEM case.
* sem_destroy.c: Likewise.
* sem_wait.c: Likewise.
* sem_post.c: Likewise.
* sem_post_multple.c: Likewise.
* implement.h: Likewise.
* sem_timedwait.c: Likewise; this routine is now
implemented for builds that define NEED_SEM (WinCE etc).
* sem_trywait.c: Likewise.
* sem_getvalue.c: Likewise.
* pthread_once.c: Yet more changes, reverting closer to Gottlob Frege's
first design, but retaining cancellation, priority boosting, and adding
preservation of W32 error codes to make pthread_once transparent to
GetLastError.
2005-04-11 Ross Johnson <ross at callisto.canberra.edu.au>
* pthread_once.c (pthread_once): Added priority boosting to
solve starvation problem after once_routine cancellation.
See notes in file.

* Makefile: Added debug targets for all versions of the library.
2005-04-01 Ross Johnson <ross at callisto.canberra.edu.au>
* GNUmakefile: Add target to build libpthreadGC1.a as a static link
library.
* Makefile: Likewise for pthreadGC1.lib.
2005-04-01 Kevin Lussier <Kevin at codegreennetworks.com>
* sem_timedwait.c (sem_timedwait): Increase size of temp variables to
avoid int overflows for large timeout values.
* implement.h (int64_t): Include or define.

2005-03-16 Ross Johnson <ross at callisto.canberra.edu.au>^M
* pthread_setcancelstate.c: Don't check for an async cancel event
if the library is using alertable async cancel..
2005-03-14 Ross Johnson <ross at callisto.canberra.edu.au>
* pthread_once.c (pthread_once): Downgrade interlocked operations to simple
memory operations where these are protected by the critical section; edit
comments.
