Details:

I tried to use a mex-file on 64-bit Octave and got memory allocation problem.
The problem was casued by the fact
that mwSize and mwIndex were defined as int in src/mxarray.h, although
configure has been ran with --enable-64
  
The following patch defines mwSize and mwIndex as long, and solves this
problem.
