No working compiler found, or bogus compiler options passed to
the compiler from Python's standard "distutils" module. See
the error messages above. Likely, the problem is not related
to CFFI but generic to the setup.py of any Python package that
tries to compile C code. (Hints: on OS/X 10.8, for errors about
-mno-fused-madd see http://stackoverflow.com/questions/22313407/
Otherwise, see https://wiki.python.org/moin/CompLangPython or
the IRC channel #python on irc.freenode.net.)
Trying to continue anyway. If you are trying to install CFFI from
a build done in a different context, you can ignore this warning.
