I almost have celerid building extension modules with dmd under cygwin. The issue now is linking to python. With normal windows, it's easy enough to convert libs/pythonXY.lib to OMF. With cygwin, we have /usr/lib/pythonX.Y/config/pythonX.Y.dll.a. Don't know what to do with that.

My brainstorms were

1) use cygwin's ld. This might work if it supports coff and I can find a way to convert omf object files to coff object files

2) screw cygwin. who uses it anyways? (other than me, because I can't stand the windows command prompt)
