Description: Fix compilation of C++ MEX files with GCC 4.8
 The header mex.h was including mexproto.h within an extern "C" block. In turn,
 mexproto.h includes cstdlib.
 .
 Apparently, including cstdlib within an extern "C" block was working with GCC
 4.7, but this is no longer the case with GCC 4.8.
 .
 The fix consists in including mexproto.h outside of the extern "C" block.
