Removed POSIX_*. Defined G_THREAD_SOURCE to "gthread-win32.c".


2001-05-22  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

        * config.h.win32.in: Removed POSIX_*. Defined G_THREAD_SOURCE to
        "gthread-win32.c".

        * glibconfig.h.win32.in: Define G_HAVE_ISO_VARARGS for gcc, don't
        know about MSC. Define G_THREADS_IMPL_WIN32 instead of
        G_THREADS_IMPL_POSIX and define the right static mutex macros and
        types.

        * build/win32/make.mingw (CXX): Removed PTHREAD defs. Added
	-O2 -Wall to compile flags.

        * gthread/gthread-impl.c (g_thread_init): Move the thread
	implementation initialization to before assigning
  	GThreadFuncs, which now is just struct assigned and not
	memcpy'ed. Completed check for zero members of GThreadFuncs.

        * gthread/makefile.mingw: Don't link to pthread anymore.

        * gthread/gthread-win32.c: New file for native thread support for
        win32. Thanks to Hans Breuer <hans@breuer.org> to got me
        kickstarted.

        * gthread/Makefile.am: Also distribute gthread-win32.c.
