changelog

this is simple sip stack.

	(pthread_cond_wait): Now just calls the internal static
	function cond_timedwait() with an INFINITE wait.
	(pthread_cond_timedwait): Now implemented. Calls the internal
	static function cond_timedwait().

	* implement.h (_pthread_sem_timedwait): New internal function
	prototype.

	* misc.c (pthreadCancelableWait): Added new 'abstime' argument
	to allow shorter than INFINITE wait.

	* semaphore.c (_pthread_sem_timedwait): New function for internal
	use.  This is essentially sem_wait() modified to add the
        'abstime' arg and call the modified (see above)
        pthreadCancelableWait().

Thu Jan 14 14:27:13 1999  Ross Johnson  <[e-mail]>

	* cleanup.c: Correct _cplusplus to __cplusplus wherever used.

	* Makefile.in: Add CC=g++ and add -fhandle-exceptions to CFLAGS.
	The derived Makefile will compile all units of the package as C++
	so that those which include try/catch exception handling should work
	properly. The package should compile ok if CC=gcc, however, exception
	handling will not be included and thus thread cancellation, for
 	example, will not work.

	* cleanup.c (_pthread_pop_cleanup): Add #warning to compile this
 	file as C++ if using a cygwin32 environment. Perhaps the whole package
	should be compiled using g++ under cygwin.

	* private.c (_pthread_threadStart): Change #error directive
	into #warning and bracket for __CYGWIN__ and derivative compilers.

Wed Jan 13 09:34:52 1999  Ross Johnson  <[e-mail]>

	* build.bat: Delete old binaries before compiling/linking.

Tue Jan 12 09:58:38 1999  Ross Johnson  <[e-mail]>

	* dll.c: The Microsoft compiler pragmas probably are more
	appropriately protected by _MSC_VER than by _WIN32.
	- Tor Lillqvist <[e-mail]>.

	* condvar.c (pthread_cond_timedwait): Fix function description
	comments.

	* pthread.h: Define ETIMEDOUT. This should be returned by
	pthread_cond_timedwait which is not implemented yet as of
	snapshot-1999-01-04-1305. It was implemented in the older version.
	The Microsoft compiler pragmas probably are more appropriately
	protected by _MSC_VER than by _WIN32.
	- Tor Lillqvist <[e-mail]>.

	* pthread.def: pthread_mutex_destroy was missing from the def file
	- Tor Lillqvist <[e-mail]>.

	* condvar.c (pthread_cond_broadcast): Ensure we only wait on threads
	if there were any waiting on the condition.
	I think pthread_cond_broadcast should do the WaitForSingleObject
	only if cv->waiters > 0? Otherwise it seems to hang, at least in the
	testg thread program from glib.
	- Tor Lillqvist <[e-mail]>. 

	* semaphore.c (sem_post): Correct typo in comment.

Mon Jan 11 20:33:19 1999  Ross Johnson  <[e-mail]>

	* pthread.h: Re-arrange conditional compile of pthread_cleanup-*
	macros.

	* cleanup.c (_pthread_push_cleanup): Provide conditional 
	compile of cleanup->prev.

1999-01-11  Ben Elliston  <[e-mail]>

	* condvar.c (pthread_cond_init): Invert logic when testing the
	return value from calloc().
	- Tor Lillqvist <[e-mail]>.

Sat Jan  9 14:32:08 1999  Ross Johnson  <[e-mail]>

	* implement.h: Compile-time switch for CYGWIN derived environments
	to use CreateThread instead of _beginthreadex. Ditto for ExitThread.
	Patch provided by Anders Norlander  <[e-mail]>.

Tue Jan  5 16:33:04 1999  Ross Johnson  <[e-mail]>

	* cleanup.c (_pthread_pop_cleanup): Add C++ version of __try/__except
	block. Move trailing "}" out of #ifdef _WIN32 block left there by
	(rpj's) mistake.

	* private.c: Remove #include <errno.h> which is included by pthread.h.

1998-12-11  Ben Elliston  <[e-mail]>

	pointer to a function. Call _pthread_try_enter_critical_section
