CygwinCCompiler seems legacy code.
In v3.4 latest rivision, Distutils has made to work that is a patching to UnixCCompiler.
So, I have a think that doesn't need to use CygwinCCompiler to build on Cygwin.
I have upload a patch for UnixCCompiler.  The patch has modified from http://cygwin.org package.

Other big issues and patches for build on Cygwin:
#21085, #13756 -- compile error
#14598, #21124 -- C extension module
