Find a GNU program written in bash (or in sh) and see how they do it.
If you like how they do it, copy their parser and use it in your
project.

If you don't like how they do it, find another way.

I believe you will find that the GNU project is quite big on portability,
and that they won't be using the Linux-only getopt program.  Remember,
the GNU project started long before Linux existed, and one of its early
strategies was to write drop-in replacements for the Unix command set.
GNU programs therefore need to work on as many different flavors of Unix
as possible, with as few disruptions as possible.

If GNU had written a getopt program, it would certainly be compatible
with the Unix version.
