 * This is a workaround for a minor swig bug when building on gcc 4.6.1 and above.
 * Prior to gcc 4.6.1 the STL headers like vector, string, etc. used to 
 * automatically pull in the cstddef header but starting with gcc 4.6.1 they no
 * longer do. This leads to swig generated a file that does not compile so we
 * explicitly include cstddef so the swig generated file will compile.
