Well, on some systems (also Darwin in some cases), Libtool uses -nostdlib in shared library creation. Wouldn't omitting gcc_s in this case cause missing symbols, at least if the output file is a module (say, it uses Fortran) and libgcc_s was not previously loaded by the main application (that, say, only uses C)? In that case it seems more appropriate to me to strip -lgcc_s from inside libtool in the cases where we know that we don't need it (i.e., when not using -nostdlib), rather than stripping it in _AC_FC_LIBRARY_LDFLAGS.
