[Jack Howarth]

   A couple changes in gcc 4.4.0 were omitted for
the darwin target. The gcc 4.4.0 release now supports
a full multilib build on the x86_64-apple-darwin9 and
x86_64-apple-darwin10 targets. The gfortran compiler
is now capable of generating binaries linked against
the static libgfortran library using the compiler option
-static-libgfortran. FYI.
