I think it was added because of symbols which appear in Apple's
libgcc.a (maybe saveFP, restFP et. al.) but don't exist in the fsf
version. The solution used to be to add -lcc_dynamic to the link
line, but with 10.4, that lib disappeared.
I'm not 100% sure though...

libgcc_dynamic always was, despite its name, a link to the static
libgcc.a, but Apple removed this link for gcc4.
If it's really just for these two symbols, maybe you should just
steal gcc/config/rs6000/darwin-fpsave.asm from 4.0.1.
Sorry to have been away during this.
Peter's recollection coincides with my vague memory:
"saveFP, restFP, et. al." _ ie not just those 2, though they were by
far the most prevalent...
