FWIW, the last gcc2 snapshot I could build (with -m586 in) typically seemed to gain about 20% on a 586 with single-precision Fortran code, roughly consistent with numbers reported by proprietary offerings at the time, though some with `pentium optimization' only seemed to perform about as well as the gcc-2.7-based g77 (generating 486 code). If people care about Fortran performance I'll eventually do some realistic tests on a 586, but have no access to a 686; this isn't necessarily trivial, though, and I'm more interested in the release of a correct g77 0.5.21 at this stage.
