fixed errernerous code wrt to thread specific error string allocation

Browse Source 
Wed Feb 10 07:56:33 1999  Tim Janik  <timj@gtk.org>

        * gmodule.c (g_module_error): fixed errernerous code wrt to thread
        specific error string allocation handling.

Wed Feb 10 06:20:30 1999  Tim Janik  <timj@gtk.org>

        * gmutex.c (g_static_private_set): invoke destroy notifier when
        overwriting values, initialize new array fields with NULL.
        (g_static_private_free_data): do not skip destroy notification for
        data == NULL.

        * gutils.c (g_direct_equal): compare pointer values directly instead
        of just their guint values which is a loosing conversion for
        sizeof(gpointer)==8 systems.
        (g_get_any_init): restructured code so we don't use endless loops like
        while (1), which boil down to an ugly alias for goto.
        strip ,.* from the real name.
