I have created a clean diff against current gcc trunk for
it and added the missing changelog. It works fine under
i686-apple-darwin9 for creating staticly linked fortran
binaries.
    Janis, could you please do the checkin so we can get
this in before the branch occurs. Thanks in advance.

        * gcc/config/darwin.h: Add static-libgfortran to LINK_SPEC.
        * libgomp/testsuite/lib/libgomp.exp: Add -B option for targets that
	use libgfortran.a%s in their specs.
        * gcc/testsuite/lib/gfortran.exp: Likewise.
