Besides the deep technicality of potential conflicts, two changes will allow you to compile your C extension. msvc9compiler.py is written only looking for VS2010, and even if you have vs2010 installed, it will still fail on Windows 7, Windows 8 with silly manifest errors.

The fix is simple:
In: Python27/Lib/distutils/msvc9compiler.py,
line#648 in definition of "link", before the call to "ld_args.append('/MANIFESTFILE:' + temp_manifest)",insert:
    ld_args.append('/MANIFEST')

line#178 in the definition of "get_build_version", insert:
    return 11.0
