The format you have chosen for the GIF extension data on MAC_OS is
completely different from the "raw" extension data which is returned for
other systems.  This makes it harder to use the data at the Lisp level.

Since it is trivial to emulate the "raw" format for the duration extension,
I would prefer if you do this, instead of using a different format.  E.g.:

unsigned char tem[4] = { 0, (duration)&0xff, ((duration)>>8)&0xff, 0 };

result = list4 (Qcount,
                make_number (images),
                make_number (0xF9),
                make_unibyte_string (tem, 4));
