mkoctfile and 64 bit

[Rishi Amrit]

Since in the first email itself you mentioned about using octave 2.1 and
octave 2.9. I wonder which one is the default. I know one thing for sure
that when you compile a .cc file with mkoctfile, it will run in only that
version of octave which you used the mkoctfile. So if you used
mkoctfile 2.9... it will run in octave
2.9 only ! .So make sure your mkoctfile and octave versions are same.
