hack to work around compatibility issue with gnulib getopt.c

[Paul Eggert]

I installed this horrible hack.  Most likely getopt should be fixed
instead....

2002-12-13  Paul Eggert  <address@hidden>

        * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
        problem with latest <getopt.h>.
        (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
