Ulrich Drepper e1f0c5bc78 * scripts/check-local-headers.sh: Filter out sys/capability.h.
2007-03-22  Jakub Jelinek  <jakub@redhat.com>

	* config.h.in (HAVE_LIBCAP): Add.
	* nscd/selinux.h: Include sys/capability.h rather than non-existent
	sys/capabilities.h.
	* nscd/selinux.c (preserve_capabilities): Use cap_free instead of
	free_caps.  Cast away const from 4th cap_set_flag argument.
