actually, Paolo's comment led to a much simpler solution.

Ironically, the need to have different library names allows  
substitution in the SPECs.  So there is no need to modify code.

so the patch becomes one line in the spec:
	gcc/config/darwin.h: substitute -lgfortran-static for -lgfortran  
when '-static-libgfortran' or '-static' are in effect

and the necessary library re-naming:
	libgfortran/Makefile.am : make separately named libgfortran-static.a  
if the host is darwin, don't generate libgfortran.a
	libgfortran/configure.ac: provide a flag on darwin systems that  
require a separately named static library

	libgfortran/Makefile.in regenerated
	libgfortran/configure regenerated

regtested -m32/-m64 on i686-apple-darwin9
regtested -m32/-m64 on powerpc-apple-darwin8
(note, that to use this -m64 on darwin8, GCC must be built with  
dwarf-2 as the default debug format).

cheers,
Iain
