This error comes from a bug in liboctave-dev.

The root of the problem is that mex.h includes mexproto.h within an
extern "C" block. In turn, mexproto.h includes cstdlib. 

Apparently, including cstdlib within an extern "C" block was working
with G++ 4.7, but this is no longer the case. 

The fix is to include mexproto.h outside of the extern "C" block.
