That message was for a much older configuration. Perhaps the
issue has been fixed since then, but since you did not attach
cygcheck.out for us to determine your configuration, I can't
tell if you need to upgrade.

If I understand right, cygwin uses assembly instructions that
won't work on a 386. But beyond that, if you have a machine
that can run Win95, then you can run cygwin (although it may
be painfully slow). I regularly run cygwin on a 266 MHz Pentium
Pro, Win98 (although I much prefer more modern machines).
