[racket-dev] Errors compiling on cygwin

To update, I went ahead and copied the macro from where it was defined for windows over to the cygwin section. The next errors were due to three consecutive assignments in schemex.inc that were accessing undefined functions (ones related to "freeze" or "frozen" - unfortunately I don't have the code right now), so I commented those lines out. Now I have a successful link, except it segfaults during make install. This is because this target runs the racketcgc (spelling?) executable, which immediately seg faults (I tried running it in the shell to be sure). 

I hope someone has more clues about this. Thank you.
