re PR libobjc/20252 (Libobjc build broken)

2005-02-28  Andrew Pinski <pinskia@physics.uc.edu>

        PR libobjc/20252
        * Makefile.in (GTHREAD_FLAGS): Remove.
        (ALL_CFLAGS): Remove usage of GTHREAD_FLAGS.
        * thr-objc.c: Include config.h.
        * configure.ac: Instead of looking at GCC's makefile, figure out if
        GTHREAD_FLAGS should be defined by looking at the `thread model'
        of the current gcc.
        * configure: Regenerate.
        * config.h.in: Regenerate.
