patch: crash when returning from mex file

[Jens Restemeier]

Hi,
I'm quite new to octave, and I didn't find a bugzilla or similar.
On my platform (OSX,PPC) I had a problem because sizeof(bool) !=  
sizeof(mxLogical), so I was getting a memory overwrite in int_to_ov.  
Easy fix:

+++ mex.cc      2013-09-13 14:46:43.000000000 +0100

     switch (get_class_id ())
       {
       case mxLOGICAL_CLASS:
-        retval = int_to_ov<bool, boolNDArray, bool> (dv);
+        retval = int_to_ov<mxLogical, boolNDArray, bool> (dv);
         break;

       case mxCHAR_CLASS:

That way it uses exactly the same source type as the mex file and the  
mxArray use.
