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.
