Adding support for x64 Windows System

Hi.
I don't if some else have the same problem but I can't compile.
I have this error.
```
build\temp.win-amd64-2.7\Release\fuzzycomt.o:fuzzycomt.c:(.text+0xaa0): undefined reference to `__imp_Py_InitModule4'
```
I have search on the web and found that adding "-D MS_WIN64" to the command resolve the problem. I have add this command to the setup.py and it's work.

I have automated that by adding some line into it.

Regards.
