* misc.c (pthreadCancelableWait): New function by John Bossom. Non-stand
ard
but provides a hook that can be used to implement cancellation points in
applications that use this library.
* pthread.h (pthread_cleanup_pop): C++ (non-WIN32) version uses
try/catch to emulate John Bossom's WIN32 __try/__finally behaviour.
In the WIN32 version __finally block, add a test for AbnormalTermination
otherwise
cleanup is only run if the cleanup_pop execute arg is non-zero. Cancella
tion
should cause the cleanup to run irrespective of the execute arg.
* condvar.c (pthread_condattr_init): Replaced by John Bossom's version.
(pthread_condattr_destroy): Replaced by John Bossom's version.
(pthread_condattr_getpshared): Replaced by John Bossom's version.
(pthread_condattr_setpshared): Replaced by John Bossom's version.
(pthread_cond_init): Replaced by John Bossom's version.
Fix comment (refered to mutex rather than condition variable).
(pthread_cond_destroy): Replaced by John Bossom's version.
(pthread_cond_wait): Replaced by John Bossom's version.
(pthread_cond_timedwait): Replaced by John Bossom's version.
(pthread_cond_signal): Replaced by John Bossom's version.
(pthread_cond_broadcast): Replaced by John Bossom's version.

to resolve compile warning from MSVC.

Re-applied Anders Norlander's patch:-
Initialize _pthread_try_enter_critical_section at startup
and release kernel32 handle when DLL is being unloaded.

* buildlib.bat: Fix args to CL when building the .DLL
* cleanup.c (_pthread_destructor_run_all): Fix TSD key management.
This is a tidy-up before TSD and Thread management is completely
replaced by John Bossom's much more elegant code.
* tsd.c (pthread_key_create): Fix TSD key management.
* global.c (_pthread_key_virgin_next): Initialise.
* build.bat: New DOS script to compile and link a pthreads app
using Microsoft's CL compiler linker.

and create pthread.lib and pthread.dll using Microsoft's CL
compiler linker.

that hadn't been checked in. Those are to finish off the original TSD management
scheme which will now start to be replaced by John Bossom's implementation.
Anders' description of his changes:-
Fixes the problem with
`TryEnterCriticalSection' on w95 systems. Instead
of directly calling `TryEnterCriticalSection' it
tries to get a pointer at DLL startup and only calls
the function if it exists. See ChangeLog for things
changed.

* implement.h (_pthread_try_enter_critical_section): New extern
* dll.c (_pthread_try_enter_critical_section): New pointer to
TryEnterCriticalSection if it exists; otherwise NULL.
* dll.c (PthreadsEntryPoint):
Initialize _pthread_try_enter_critical_section at startup
and release kernel32 handle when DLL is being unloaded.
* mutex.c (pthread_mutex_trylock): Replaced check for NT with
a check if _pthread_try_enter_critical_section is valid
pointer to a function. Call _pthread_try_enter_critical_section
instead of TryEnterCriticalSection to avoid errors on Win95.
