Thanks for the patch, but this gives me:
> +#define _BSD_SOURCE
In file included from /usr/include/bits/libc-header-start.h:33:0, from /usr/include/stdlib.h:25,
from xtables-monitor.c:13: /usr/include/features.h:184:3:
# warning "_BSD_SOURCE and # _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"
build does complete though.
Does _DEFAULT_SOURCE work for older glibc as well?
