'easy_install -U cython' fails complaining about vcvarsall.bat and -mno-cygwin


After more some googling, I found guidance that recommended removing -mno-cygwin from C:\Python27\Lib\distutils\cygwinccompiler.py because of a distutils bug.

Removing -mno-cygwin from C:\Python27\Lib\distutils\cygwinccompiler.py got cython to compile.
