Renamed GLIB_SIZEOF_PTHREAD_T to GLIB_SIZEOF_SYSTEM_THREAD to reflect

Browse Source 
1999-11-16  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

        * acconfig.h, config.h.win32.in, configure.in: Renamed
        GLIB_SIZEOF_PTHREAD_T to GLIB_SIZEOF_SYSTEM_THREAD to reflect
        changed meaning.

        * configure.in: Cope with systems, that have a pthread_t type,
        that is not a pointer. Hint from Karl Nelson
        <kenelson@ece.ucdavis.edu>. Define GLIB_SIZEOF_SYSTEM_THREAD to 4
        for Solaris. Cope with systems, that have no default mutex
        initialize, like obviously most DCE systems.

        * glib.h, gthread.c: Changed the prototype of thread_create and
        thread_self to return the system thread into provided memory
        instead of a return value. This is necessary, as HPUX has a
        pthread_t, that is bigger than the biggest integral type there.

        * gthread.c: system_thread is no longer a pointer, but an memory
        area of size GLIB_SIZEOF_SYSTEM_THREAD. Changed the
        zeroinitialization and the tests for zeroness accordingly.
