[racket-dev] Errors compiling on cygwin

Yes, our Cygwin support has rotted in a variety of small but exotic
ways.

I'm in the process of fixing the problems. The enclosed patch applies
to the development branch or the v6.1.1 release candidate, and it might
work for you, but I'm still checking it.

The fixed-up implementation will be limited in various ways, such as
not supporting places or futures, but I should be able to make all the
basics work.
