	native compilation under Win32.

	* cleanup.c (_pthread_destructor_push): Implement. This is just a
	call to _pthread_handler_push().
	(_pthread_destructor_pop_all): Implement. This is significantly
	different to _pthread_handler_pop_all().

	* Makefile (SRCS): Create. Preliminary.

	* windows.h: Create. Contains Win32 definitions for compile

	* implement.h (_pthread_threads_thread): Rename, remove thread
	member, add win32handle and ptstatus members.
	(_pthread_t): Add.

	* pthread.h: pthread_t is no longer mapped directly to a Win32
	HANDLE type. This is so we can let the Win32 thread terminate and
	reuse the HANDLE while pthreads holds it's own thread ID until
	the last waiting join exits.

	* pthread.h: Converting PTHREAD_* defines to alias the (const int)
	values in global.c.

	* global.c: Started converting PTHREAD_* defines to (const int) as
 	a part of making the eventual pthreads DLL binary compatible
 	through version changes.

	* condvar.c (cond_wait): Add cancelation point. This applies the
	point to both pthread_cond_wait() and pthread_cond_timedwait().

	* exit.c (pthread_exit): Rename "this" to "us".

	* implement.h: Add comment.

	* sync.c (pthread_join): I've satisfied myself that pthread_detach()
	does set the detached attribute in the thread entry attributes
	to PTHREAD_CREATE_DETACHED. "if" conditions were changed to test
	that attribute instead of a separate flag.

	* create.c (pthread_create): Rename "this" to "us".
	(pthread_create): cancelstate and canceltype are not attributes
	so the copy to thread entry attribute storage was removed.
	Only the thread itself can change it's cancelstate or canceltype,
	ie. the thread must exist already.

	* private.c (_pthread_delete_thread_entry): Mutex locks removed.
	Mutexes must be applied at the caller level.
	(_pthread_new_thread_entry): Ditto.
	(_pthread_new_thread_entry): Init cancelstate, canceltype, and
	cancel_pending to default values.
	(_pthread_new_thread_entry): Rename "this" to "new".

	* create.c (_pthread_start_call): Mutexes changed to
	_pthread_count_mutex. All access to the threads table entries is
	under the one mutex. Otherwise chaos reigns.

	* fork.c (pthread_atfork): Add all the necessary push calls.
	Local implementation semantics:
	If we get an ENOMEM at any time then ALL handlers
	(including those from previous pthread_atfork() calls) will be

	pthread_exit() to use.

	* private.c (_pthread_new_thread_entry): Initialise joinvalueptr to

	* private.c (_pthread_new_thread_entry): _pthread_thread_table
	was changed back to a table of thread structures rather than pointers.
	As such we're trading storage for increaded speed. This routine
	was modified to work with the new table. Mutex lock put in around
	global data accesses.
	(_pthread_find_thread_entry): Ditto
	(_pthread_delete_thread_entry): Ditto

	all new threads. It allows us to do some cleanup when the thread
	returns, ie. that is otherwise only done if the thread is cancelled.

	pthread_exit() that we need in the new _pthread_start_call()
	as well.

	* implement.h: Various additions and minor changes.

	These are private to the implementation. The real cleanup functions
	are macros. See below.

	* pthread.h (pthread_cleanup_push): Implement as a macro.
	(pthread_cleanup_pop): Implement as a macro.
	Because these are macros which start and end a block, the POSIX scoping
	requirement is observed. See the comment in the file.

	Keep a thread-private copy of the attributes with default values
	filled in when necessary. Same for the cleanup stack. Make 
	pthread_create C run-time library friendly by using _beginthreadex()
	instead of CreateThread(). Fix error returns.

Sun Jul 19 16:26:23 1998  Ross Johnson  <rpj@ixobrychus.canberra.edu.au>

	* implement.h: Rename pthreads_thread_count to _pthread_threads_count.
	Create _pthread_threads_thread_t struct to keep thread specific data.

	* create.c: Rename pthreads_thread_count to _pthread_threads_count.
	(pthread_create): Handle errors from CreateThread().

1998-07-19  Ben Elliston  <bje@cygnus.com>

	* condvar.c (pthread_cond_wait): Generalise.  Moved from here ..
	(cond_wait): To here.
	(pthread_cond_timedwait): Implement; use generalised cond_wait().

	* pthread.h (pthread_key_t): Define this type.
	(pthread_key_create): Add function prototype.
	(pthread_setspecific): Likewise.
	(pthread_getspecific): Likwise.

	* tsd.c (pthread_key_create): Implement.
	(pthread_setspecific): Likewise.
	(pthread_getspecific): Likewise.
	(pthread_key_delete): Likewise.

	* mutex.c (pthread_mutex_trylock): Return ENOSYS if this function
	is called on a Win32 platform which is not Windows NT.

1998-07-18  Ben Elliston  <bje@cygnus.com>

	* condvar.c (pthread_condattr_init): Do not attempt to malloc any
	storage; none is needed now that condattr_t is an empty struct.
	(pthread_condattr_destory): Likewise; do not free storage.
	(pthread_condattr_setpshared): No longer supported; return ENOSYS.
	(pthread_condattr_getpshared): Likewise.
	(pthread_cond_init): Implement with help from Douglas Schmidt.
	Remember to initialise the cv's internal mutex.
	(pthread_cond_wait): Likewise.
	(pthread_cond_signal): Likewise.
	(pthread_cond_broadcast): Likewise.
	(pthread_cond_timedwait): Preliminary implementation, but I need
	to see some API documentation for `WaitForMultipleObject'.
	(pthread_destory): Implement.

	* pthread.h (pthread_cond_init): Add function protoype.
	(pthread_cond_broadcast): Likewise.
	(pthread_cond_signal): Likewise.
	(pthread_cond_timedwait): Likewise.
	(pthread_cond_wait): Likewise.
	(pthread_cond_destroy): Likewise.
	(pthread_cond_t): Define this type.  Fix for u_int.  Do not assume
	that the mutex contained withing the pthread_cond_t structure will
	be a critical section.  Use our new POSIX type!

	* implement.h (_pthread_condattr_t): Remove shared attribute.

1998-07-17  Ben Elliston  <bje@cygnus.com>

	* pthread.h (PTHREADS_PROCESS_PRIVATE): Remove.
	(PTHREAD_PROCESS_SHARED): Likewise.  No support for mutexes shared
	across processes for now.
	(pthread_mutex_t): Use a Win32 CRITICAL_SECTION type for better
	* implement.h (_pthread_mutexattr_t): Remove shared attribute.
	* mutex.c (pthread_mutexattr_setpshared): This optional function
	is no longer supported, since we want to implement POSIX mutex
	variables using the much more efficient Win32 critical section
	primitives.  Critical section objects in Win32 cannot be shared
	between processes.
	(pthread_mutexattr_getpshared): Likewise.
	(pthread_mutexattr_init): No need to malloc any storage; the
	attributes structure is now empty.
	(pthread_mutexattr_destroy): This is now a nop.
	(pthread_mutex_init): Use InitializeCriticalSection().
	(pthread_mutex_destroy): Use DeleteCriticalSection().
	(pthread_mutex_lock): Use EnterCriticalSection().
	(pthread_mutex_trylock): Use TryEnterCriticalSection().  This is
	not supported by Windows 9x, but trylock is a hack anyway, IMHO.
	(pthread_mutex_unlock): Use LeaveCriticalSection().
