mingw下编译pycrypto出现-mno-cygwin错误

唉，windows下装东西真麻烦。

在PYTHON安装目录，找到/lib/distutils/cygwinccompiler.py,我记得有3-4处，把-mno-cygwin，删除，就行了。

注意！删除cygwinccompiler.pyc文件

It sounds like GCC 4.7.0 has finally removed the deprecated -mno-cygwin option, but distutils has not yet caught up with it. Either install a slightly older version of MinGW, or edit distutils\cygwinccompiler.py in your Python directory to remove all instances of -mno-cygwin
