Follow-up Comment #2, bug #29794 (project octave):
I don't see how configure would get a different result for the size of an
integer since it uses the C compiler to perform the check.
If the source of the error is a configure problem, then what version of
autoconf are you using?
Also, for full compatibility I think we should have the following definitions
on 32-bit systems:
mwSize int
mwIndex int
mwSignedIndex ptrdiff_t
and the following definitions on 64-bit systems:
mwSize size_t
mwIndex size_t
mwSignedIndex ptrdiff_t
(these values are from the Matlab docs on the web).
But since these definitions have to work with our definition for
octave_idx_type, I think we should revive the following discussion on the
maintainers list before deciding exactly how to fix it:
