        * Several: Fix typos from scripted edit session
        yesterday.

        * nonportable.c (pthread_mutexattr_setforcecs_np):
        Moved this function from mutex.c.
        (pthread_getw32threadhandle_np): New function to
        return the win32 thread handle that the POSIX
        thread is using.
        * mutex.c (pthread_mutexattr_setforcecs_np):
        Moved to new file "nonportable.c".

        * pthread.h (PTW32_BUILD): Only redefine __except
        and catch compiler keywords if we aren't building
        the library (ie. PTW32_BUILD is not defined) -
        this is safer than defining and then undefining
        if not building the library.
        * implement.h: Remove __except and catch undefines.
        * Makefile (CFLAGS): Define PTW32_BUILD.
        * GNUmakefile (CFLAGS): Define PTW32_BUILD.

        * All appropriate: Change Pthread_exception* to
        ptw32_exception* to be consistent with internal
        identifier naming.

        * private.c (ptw32_throw): New function to provide
        a generic exception throw for all internal
        exceptions and EH schemes.
        (ptw32_threadStart): pthread_exit() value is now
        returned via the thread structure exitStatus
        element.
        * exit.c (pthread_exit): pthread_exit() value is now
        returned via the thread structure exitStatus
        element.
        * cancel.c (ptw32_cancel_self): Now uses ptw32_throw.
        (pthread_setcancelstate): Ditto.
        (pthread_setcanceltype): Ditto.
        (pthread_testcancel): Ditto.
        (pthread_cancel): Ditto.
        * misc.c (CancelableWait): Ditto.
        * exit.c (pthread_exit): Ditto.
        * All applicable: Change PTW32_ prefix to
        PTW32_ prefix to remove leading underscores
        from private library identifiers.

 New:

--	Renamed DLL and LIB files:

-		pthreadVSE.dll	(MS VC++/Structured EH)

-		pthreadVSE.lib

-		pthreadVCE.dll	(MS VC++/C++ EH)

-		pthreadVCE.lib

-		pthreadGCE.dll	(GNU G++/C++ EH)

-		libpthreadw32.a

-

-	Both your application and the pthread dll should use the

-	same exception handling scheme.

+-	New non-portable function (see the README file):

+		pthread_getw32threadhandle_np

 

 Bugs fixed:

--	MSVC++ C++ exception handling.

+-	TSD key creation race condition;

+-	Other potential race conditions

+	associated with initialising various

+	pthreads objects.

 

 Some new tests have been added.

+2. Running the test "join1.c" with the library built with Mingw32

 and the GNUmakefile included, the test fails with a segmentation (invalid

 page access) exception. The fault appears to be in the assembler code

 emmitted by the compiler [to handle exception contexts] at the

 end of the try block in ptw32_threadStart().
