Does the check fail if the integer sizes don't match?

Yes, this should be done so that the Fortran code that is distributed
with Octave will compile correctly, but we also need to check all
other libraries that we link with and that we pass octave_idx_type
values to.  What's the best way to do that?  I assume it will require
running test programs.  Maybe we should move any further discussion to
the maintainers list?
