I've played with Cygwin the last couple of days. I've discovered tha 
haven't checked the patch in, so I'll check in an updated version soon. 
This doesn't mean that I've got Cygwin support working, it just means 
that I'm fixing build issues as I encounter them. Unfortunately, it 
takes ages for Cygwin to build kaffe on my p3-600 with win98, and some 
of the configure checks seem to be able to put win98 in a weird state.

Which is what I intend to try.
