From 01885f533de81ff73e9da1519a4b5f2316b49f86 Mon Sep 17 00:00:00 2001
From: Sebastian Huber <sebastian.huber@embedded-brains.de>
Date: Mon, 14 Dec 2015 10:06:18 +0100
Subject: FreeBSD compatibility for <sys/select.h>

	* libc/include/sys/_sigset.h: New.
	* libc/include/sys/select.h: Do not include <sys/types.h> and
	<sys/time.h> to avoid cyclic header file dependencies.  Include
	specialized header files instead.
	(sigset_t): Conditionally define.
	* libc/include/sys/signal.h (sigset_t): Likewise.
	* libc/include/sys/time.h: Include <sys/select.h> if
	__BSD_VISIBLE.
	* libc/include/sys/types.h: Likewise.
