This list of machines serves both as a list of computers to which RIPEM
has been ported, and a measure of the performance of the various
platforms.

The benchmark in question is from "make benchmark"; RIPEM generates
a particular 516-bit key.

In this I list the fastest time I've yet recorded for the various
platforms after a little bit of twiddling with compilers and,
in some cases, introducing assembly code (as noted).
I'd be interested in 386/486 timings with a decent compiler.
I realize that in some cases, mediocre compilers hampered performance.

Note: Beta-8 introduced Mark Henderson's BIGNUM speedup that
improves performance by about 15%. Unmarked entries are pre-Beta-8
and should be compensated for accordingly. Also, some versions
have critical routines in assembly code, as noted.

Times are in seconds; user time + system time.
