I agree.

This is really a pseudo cross-compile and would be better handled IMO as a true
canadian-cross so that the headers and support libs aren't in the same
directory.

Well actually, I've wondered about adding unix and linux and 'similar
"standard" defines' myself.  What would you consider "standard"?

I have modified my specs file to remove the defines for _WIN32 and WINNT.  I've
thought of adding unix type defines but haven't yet.
