Oh - one more thing. hsc2hs needs to be done by hand on Cygwin. You cannot allow it to try and built through because the last step (executing the .exe redirected to the .hs) will fail and that cannot be cygpath'ed (I don't think). Having the makefile execute each step separately may be a good option. I can try to cygpath the filenames before they get passed to hsc2hs, but I don't think that's best.
