To prepend (for example "vlc_") to every non-static function of
libvlccore it is not an acceptable solution (for 1.2 of course)?

An other way is to reimplement without getopt.. at least, the parser
itself can be copied from the sources of getopt.
It looks perfectly doable but I understand if it is not a priority.
getopt is mostly (only?) used in src/config/cmdline.c, I'm right?
