GNU packages make a point of including source for any library function
that is not provided by more-or-less standard libraries on Unix
systems.  So every GNU package comes with files getopt.[ch] and
getopt1.c which support the long options functionality.  If you don't
care about GPL/LGPL issue, just lift the code from a source zip of any
GNU package in v2gnu.
