  Here the rewritten patch is.  __PRO__ is now always defined for
hppa1.1-*-pro* and hppa1.1-*-rtems*.  Please ignore the previous patch
(__PRO__ was used only for libgcc compilation in it).

2002-03-26  Vladimir Makarov  <vmakarov@redhat.com>

        * pa/pa-pro-end.h (CPP_PREDEFINES): Add -D__PRO__.

        * pa/lib2funcs.asm: Don't use .SPACE and .SUBSPACE if __PRO__ is
        defined.
