Thanks for the patch. It seems useful for people with old or non-GNU
systems. Here are my comments to your modifications:

Renaming functions may be useful for some people, but please,
understand that I won't change Ocrad to adap it to a non
standards-compliant compiler. Even if it is an old version of gcc.

I am thinking about an alternative to getopt_long for systems lacking
it, but in any case the default behavior will be to use it. GNU Ocrad
should run "out of the box" on current GNU systems, and modified on
other systems, not the other way round.


Best regards,
