The subject and body of your message implies that you are looking for a
way to statically compile cygpath.  I was responding to tell you that
1) It isn't possible and 2) You'd have GPL concerns if you did that.

If you are just looking to figure out paths in a non-cygwin-make then I
think your best bet would be to test for the existence of a cygpath and
use that.
