[autoconf] GNU_SOURCE can be defined twice, through AC_FUNC_STRNLEN
2007-05-10 Paul Jakma <paul.jakma@sun.com>
* configure.ac: Use AC_GNU_SOURCE to define _GNU_SOURCE, rather
than having lib/zebra.h do it.
AC_FUNC_STRNLEN has side-effects with latest autoconf, use
AC_CHECK_FUNC on strnlen instead.
* lib/zebra.h: Don't try define _GNU_SOURCE, autoconf should do it.
