	* pthread.h (rand_r): Fake using _seed argument to quell
	compiler warning (compiler should optimise this away later).

	* GNUmakefile (OPT): Leave symbolic information out of the library
	and increase optimisation level - for smaller faster prebuilt
	dlls.

	* Makefile: fix typo.
	* pthreads.h: Fix problems with stdcall/cdecl conventions, in particular
	remove the need for PT_STDCALL everywhere; remove warning supression.
	* (errno): Fix the longstanding "inconsistent dll linkage" problem
	with errno; now also works with /MD debugging libs -
	warnings emerged when compiling pthreads library with /MD (or /MDd)
	compiler switch, instead of /MT (or /MTd) (i.e. when compiling pthreads
	using Multithreaded DLL CRT instead of Multithreaded statically linked
	CRT).
	* create.c (pthread_create): Likewise; fix typo.
	* private.c (ptw32_threadStart): Eliminate use of terminate() which doesn't
	throw exceptions.
	* Remove unnecessary #includes from a number of modules -
	[I had to #include malloc.h in implement.h for gcc - rpj].

	* pthread.h (PTHREAD_MUTEX_DEFAULT): New; equivalent to
	PTHREAD_MUTEX_DEFAULT_NP.
	* (PTHREAD_MUTEX_NORMAL): Similarly.
	* (PTHREAD_MUTEX_ERRORCHECK): Similarly.
	* (PTHREAD_MUTEX_RECURSIVE): Similarly.
	* (pthread_mutex_setdefaultkind_np): New; Linux compatibility stub
	for pthread_mutexattr_settype.
	* (pthread_mutexattr_getkind_np): New; Linux compatibility stub
	for pthread_mutexattr_gettype.
	* mutex.c (pthread_mutexattr_settype): New; allow
	the following types of mutex:
	  PTHREAD_MUTEX_DEFAULT_NP
	  PTHREAD_MUTEX_NORMAL_NP
	  PTHREAD_MUTEX_ERRORCHECK_NP
	  PTHREAD_MUTEX_RECURSIVE_NP
	* Note that PTHREAD_MUTEX_DEFAULT is equivalent to
	PTHREAD_MUTEX_NORMAL - ie. mutexes should no longer
	be recursive by default, and a thread will deadlock if it
	tries to relock a mutex it already owns. This is inline with
	other pthreads implementations.
	* (pthread_mutex_lock): Process the lock request
	according to the mutex type.
	* (pthread_mutex_init): Eliminate use of Win32 mutexes as the
	basis of POSIX mutexes - instead, a combination of one critical section
	and one semaphore are used in conjunction with Win32 Interlocked* routines.
	* (pthread_mutex_destroy): Likewise.
	* (pthread_mutex_lock): Likewise.
	* (pthread_mutex_trylock): Likewise.
	* (pthread_mutex_unlock): Likewise.
	* Use longjmp/setjmp to implement cancelation when building the library
	using a C compiler which doesn't support exceptions, e.g. gcc -x c (note
	that gcc -x c++ uses exceptions).
	* Also fixed some of the same typos and eliminated PT_STDCALL as
	Milan Gardian's patches above.

	* rwlock.c: Revamped.
	* implement.h (pthread_rwlock_t_): Redefined.
	This implementation does not have reader/writer starvation problem.
	Rwlock attempts to behave more like a normal mutex with
	races and scheduling policy determining who is more important;
	It also supports recursive locking,
	has less synchronization overhead (no broadcasts at all,
	readers are not blocked on any condition variable) and seem to
	be faster than the current implementation [W98 appears to be
	approximately 15 percent faster at least - on top of speed increase
	from Thomas Pfaff's changes to mutex.c - rpj].
