* acinclude.m4 (LIBGFOR_CHECK_PRAGMA_WEAK): Rename to...
(LIBGFOR_GTHREAD_WEAK): ... this. Define SUPPORTS_WEAK rather
than HAVE_PRAGMA_WEAK. Define GTHREAD_USE_WEAK to 0 on hosts
that shouldn't use weak in gthr.h.
* configure.ac: Use LIBGFOR_GTHREAD_WEAK instead of
LIBGFOR_CHECK_PRAGMA_WEAK.
* config.h.in: Regenerated.
* configure: Regenerated.
* io/io.h (SUPPORTS_WEAK): Don't define here.
