[gomp] Tiny merge fixes for libgfortran

[Jakub Jelinek]

Hi!

1) on gomp branch, -D_GNU_SOURCE is already in the Makefile.  As is
in fpu.c it doesn't do anything anyway, since HAVE_FENV_H is something
defined just in config.h which hasn't been included at that point yet.
2) a warning fix for find_file

2005-10-25  Jakub Jelinek  <jakub@redhat.com>

	* runtime/fpu.c (_GNU_SOURCE): Don't define here.
	* io/unix.c (find_file): Pass &st[0] to stat instead of &st.
