* tsd1.c: Re-written. See comments at start of file.

With this update I'm able to build the library and build and run the
tsd1.c test successfully using buildlib.bat and build.bat scripts.
I not convinced that I understand the relationships between "__cplusplus" and
"_WIN32" and the MS compiler, particularly in pthread.h where
pthread_cleanup_push etc is defined. In particular, I have assumed that
the __try/__finally blocks are only available if _WIN32 and __cplusplus
are defined. I suspect this is wrong.
Tue Dec 29 13:11:16 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>
* implement.h: Move the following struct definitions to pthread.h:
pthread_t_, pthread_attr_t_, pthread_mutex_t_, pthread_mutex_t_,
pthread_mutexattr_t_, pthread_key_t_, pthread_cond_t_,
pthread_condattr_t_, pthread_once_t_.
* pthread.h: Add "_" prefix to pthread_push_cleanup and
pthread_pop_cleanup internal routines, and associated struct and
typedefs.
* buildlib.bat: Add compile command for semaphore.c

(pthread_setschedparam): Change thread validation and rename "thread"
Win32 thread Handle element name to match John Bossom's version.
(pthread_getschedparam): Ditto.
* private.c (_pthread_threadDestroy): Rename call to
callUserDestroyRoutines() as _pthread_callUserDestroyRoutines()
* misc.c: Add #include "implement.h".

version to correspond to original, so that it can be used with
original attr routines.

* 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.

tion
should cause the cleanup to run irrespective of the execute arg.

As well as patches from Anders, this commit includes some older changes
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.
1998-12-05 Anders Norlander <anorland@hem2.passagen.se>
* 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.
Sun Nov 15 21:24:06 1998 Ross Johnson <rpj@ixobrychus.canberra.edu.au>

succeeds and set the key value to NULL.
