        Right - which is why there is 'libgnugetopt' in the FreeBSD ports. 
        Couple project I've dealt with over the years have just used that
        for BSD systems.

        Sigh, but yep.

        AC_CHECK_HEADER(unistd.h,getopt.h)

#ifdef HAVE_UNISTD_H
#include <unistd.h>
#endif
#ifdef HAVE_GETOPT_H
#include <getopt.h>
#endif

        and avoid specific  version checking.
