2016-12-18 Ross Johnson <ross dot johnson at homemail dot com dot au>
* implement.h (PTW32_TEST_SNEAK_PEEK): Defined in tests/test.h
to control what some tests see when sneaking a peek inside this
header.
* GNUMakefile.in: call tests "make realclean"
2016-12-17 Ross Johnson <ross dot johnson at homemail dot com dot au>
* _ptw32.h: MINGW(all) include stdint.h to define all specific
size integers (int64_t etc).
2016-12-17 Kyle Schwarz <kyle dot r dot schwarz at gmail dot com>
* _ptw32.h: MINGW6464 define pid_t as __int64.
2016-04-01 Ross Johnson <ross dot johnson at homemail dot com dot au>
* _ptw32.h: Move more header stuff into here.
* pthread.h: Move stuff from here into _ptw32.h.
* implement.h: Likewise.
* sched.h (struct timespec): Wrap with extra condition check.
* pthread_win32_attach_detach.c: Source stdlib.h to define
_countof et. al.
2016-03-31 Keith Marshall <MinGW32 project>
* aclocal.m4: New from MinGW32 patches for autoconf.
* configure.ac: Likewise.
* GNUmakefile.in: Likewise.
* install-sh: Likewise.
* _ptw32.h: Likewise.
* implement.h: Patched.
* pthread.h: Patched.
* sched.h: Patched.
* sem_open.c: Patched.
* semaphore.h: Patched.
* pthread_self.c: Patched.
2016-03-28 Ross Johnson <ross dot johnson at homemail dot com dot au>
* ptw32_relmillisecs.c (pthread_win32_getabstime_np): New
platform-aware function to return the current time plus optional
offset.
* pthread.h (pthread_win32_getabstime_np): New exported function.
* ptw32_timespec.c: COnditionally compile only if NEED_FTIME config
flagged.
* sched.h: Update platform config flags for applications.
* semaphore.h: Likewise.
* pthread.h: Likewise.
2016-03-25 Bill Parker <wp02855 at gmail dot com>
* pthread_mutex_init.c: Memory allocation of robust mutex element
was not being checked.
2016-02-29 Ross Johnson <ross dot johnson at homemail dot com dot au>

2016-02-29 Keith Marshall <keithmarshall at users dot sourceforge dot net>
* ptw32_timespec.c: Fix C90 warnings from GCC; int64_t -> uint64_t
2016-02-18 Carey Gister <careygister at outlook dot com>
* dll.c (DllMain): Should not be defined for static library builds.
Doing so prevents static linking with a dll library.
2015-11-01 Anurag Sharma <anurags at fb dot com>
* ptw32_MCS_lock.c: Fix a race condition causing crashes.
This race condition was also analysed and reported with a slightly
different fix independently by Jonathan Brown at VMware.
2015-11-01 Mark Smith <masmith at fb dot com>
* ptw32_relnillisecs.c: Fix erroneous 0-time waits, symptomizing as
busy-spinning eating CPU. When the time to wait is specified to be less
than 1 millisecond were erroneously rounded down to 0; Modify WinCE
dependency.
* ptw32_timespec.c: Remove NEED_FTIME conditionality.
2015-06-31 Dimitry <>
* sem_init.c: Remove double free() when NEED_SEM defined (for
early versions of WinCE).
2014-05-29 Ross Johnson <ross dot johnson at homemail dot com dot au>
* autostatic.c: Move content to dll.c so autostatic no longer required.
* dll.c: Include content from autostatic.c.

* Makefile (realclean): delete make.log.txt if present.
* GNUMakefile (realclean): Likewise.
2014-05-28 Jaeeun Choi <jaeeun at mdstec dot com>
* pthread_mutex_init.c: Check and free malloced robustNode element if
init is returning an ENOSPC error.
2013-12-10 Ross Johnson <ross dot johnson at homemail dot com dot au>
* Makefile (*-small-static): Removed all small-static targets in the MS
toolchain builds due to failures of TLS in apps linked with these
library builds, specifically fails tests/semaphore3.c. The other static
builds pass this test.
* dll.c: Remove unused MinGW static linking hooks; See autostatic.c.
Hope to incorporate a working set of hooks here for gcc that supports
PIMAGE_TLS_CALLBACK later at which point autostatic.c will be required
only for older compilers.
2013-12-09 Ross Johnson <ross dot johnson at homemail dot com dot au>
* Makefile (.rc.res): Add logic to extract target CPU from different
environments.
2013-07-23 Keith Clanton <keith dot clanton at cloudcar dot com>
* create.c: Don't apply cpu affinity from thread attributes for WINCE;
bug fix.
2013-07-23 Ross Johnson <ross dot johnson at homemail dot com dot au>
* config.h (HAVE_CPU_AFFINITY): Defined.
* several (WINCE): Substitute HAVE_CPU_AFFINITY where appropriate.

2013-06-19 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread_attr_init.c: Initialise thread name element.
* create.c: Initialise thread name from attributes.
2013-06-13 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread_setname_np.c: Initial version.
* pthread_getname_np.c: Initial version.
* pthread_attr_setname_np.c: Initial version.
* pthread_attr_getname_np.c: Initial version.
* pthread.h: Add new prototypes.
* implement.h (pthread_attr_t_): Add "thrname" element.
* (ptw32_thread_t): Add "name" element.
2013-06-06 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread.h (_POSIX_THREAD_ATTR_STACKADDR): Now set to -1. The API
prototypes are defined but return ENOSYS; previously the addr value was
stored in the attribute struct and retreivable but unused.
* pthread_attr_setstackaddr.c: Should return ENOSYS rather than silently
ignore the setting.
* pthread_attr_getstackaddr.c: Likewise.
* pthread_attr_getaffinity_np.c: Initial version.
* pthread_attr_setaffinity_np.c: Initial version.
2013-05-01 Andrew Chernow <achernow at gmail dot com>

Fix function calls involving TCHAR.
2012-10-29 Ross Johnson <ross dot johnson at homemail dot com dot au>

* pthread_win32_attach_detach_np.c: For WinCE don't restrict QUserEx.dll
search to system path.
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

* 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.

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.

attach/detach routines.
2012-09-05 Daniel Richard. G <danielg at teragram dot com>

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.
(VCE-static): Add VC++ static build target.
(VCE-small-static): Likewise.
(VCE-small-static-debug): Likewise.
(VCE-small-static-debug): Likewise.

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".
2012-08-29 Ross Johnson <ross dot johnson at homemail dot com dot au>
* ptw32_MCS_lock.c (ptw32_mcs_flag_wait): Fix cast in first 'if' statement.

useful help when "make" is run without a target argument.
2012-08-11 Daniel Richard. G <danielg at teragram dot com>
* autostatic.c (ptw32_autostatic_anchor): new function; other
changes aimed at de-abstracting functionality.
* impliment.h (ptw32_autostatic_anchor): dummy reference to
ensure that autostatic.o is always linked into static applications.

2012-03-19 Ross Johnson <ross dot johnson at homemail dot com dot au>
* implement.h: Fix interlocked pointer casting under VC++ x64.
2012-03-19 Ross Johnson <ross dot johnson at homemail dot com dot au>

* Bmakefile: Include new common.mk
* Makefile: Likewise; various fixes; added normal and small objects
static build.
* GNUmakefile: Likewise.
2012-03-18 Ross Johnson <ross dot johnson at homemail dot com dot au>
* create.c (pthread_create): add __cdecl attribute to thread routine
arg
* implement.h (pthread_key_t): add __cdecl attribute to destructor
element
(ThreadParms): likewise for start element
* pthread.h (pthread_create): add __cdecl to prototype start arg

* ptw32_threadStart.c (start): add __cdecl to start variable type
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.
* sem_timedwait.ci (pragma inline_depth): Likewise.
* sem_wait.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>
* Makefile (_WIN32_WINNT): Removed; duplicate definition in
implement.h; more cleanup and enhancements.
2011-07-02 Daniel Richard G. <skunk at iskunk dot org>
* Makefile: Cleanups and implovements.
* ptw32_MCS_locks.c: Casting fixes.
* 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.
* implement.h (MCS locks): nextFlag and waitFlag are now HANDLE type.
* ptw32_MCS_locks.c: Likewise.
* pthread.h (#include <setjmp.h>): Removed.
* ptw32_throw.c (#include <setjmp.h>): Added.
* ptw32_threadStart.c (#include <setjmp.h>): Added.
* implement.h (#include <setjmp.h>): Added.
2011-06-30 Ross Johnson <ross dot johnson at homemail dot com dot au>
* pthread_once.c: Tighten 'if' statement casting; fix interlocked
pointer cast for 64 bit compatibility (missed yesterday); remove
the superfluous static cleanup routine and call the release routine
directly if popped.
* create.c (stackSize): Now type size_t.
* pthread.h (struct ptw32_thread_t_): Rearrange to fix element alignments.
2011-06-29 Daniel Richard G. <skunk at iskunk dot org>
* ptw32_relmillisecs.c (ftime):
_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>
* Makefile (CC): Define CC to allow use of other compatible
compilers such as the Intel compilter icl.

2011-05-11 Ross Johnson <ross.johnson at homemail.com.au>
* ptw32_callUserDestroyRoutines.c (terminate): Altered includes
to match ptw32_threadStart.c.
* 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.
2011-03-25 Ross Johnson <ross.johnson at homemail.com.au>
* (cancelLock): Convert to an MCS lock and rename to stateLock.
* (threadLock): Likewise.

* pthread_mutex*.c: First working robust mutexes.
2011-03-11 Ross Johnson <ross.johnson at homemail.com.au>
* implement.h (PTW32_INTERLOCKED_*CREMENT macros): increment/decrement
using ++/-- instead of add/subtract 1.
* ptw32_MCS_lock.c: Make casts consistent.
2011-03-09 Ross Johnson <ross.johnson at homemail.com.au>

2011-03-06 Ross Johnson <ross.johnson at homemail.com.au>
* several (MINGW64): Cast and call fixups for 64 bit compatibility;
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.
* sched_getscheduler.c: Likewise.
* pthread.h: Remove POSIX compatibility macros; don't define
timespec if already defined.

* pthread_cancel.c: Likewise.
* 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
names to avoid using C++ keyword ("new").

* pthread_barrier_wait.c: Fix signed/unsigned comparison warning.
2010-06-18 Ramiro Polla <ramiro.polla at gmail.com >

libary init/cleanup routines automatically on application start
when statically linked.
* pthread.c (autostatic.c): Included.

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

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.

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.

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>

fix incorrect return of EBUSY resulting from the mutex trylock
on the private mutex guard.

_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 \
RANLIB=i586-mingw32msvc-ranlib clean GC-static
2005-05-13 Ross Johnson <ross at callisto.canberra.edu.au>
* 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
