matplotlib 1.2.0 doesn't compile with Solaris Studio 12.3 CC

Unlike the matplotlib 1.1.0 release, which compiles seamlessly with the Solaris Studio 12.3
CC compiler (with a few caveats related to linking as described in http://www.timswast.com/blog/2012/08/06/compiling-matplotlib-with-solaris-studio/), the 1.2.0 release fails to compile
immediately:

building 'matplotlib.ft2font' extension

Since I don't know any C++, I've no idea what's wrong, but it would be good to restore
compilation with non-g++ compilers.

Thanks.
