From 955fbf32118a00cdda8781e90553ea18ae4d819c Mon Sep 17 00:00:00 2001
From: Jim Meyering <jim@meyering.net>
Date: Thu, 5 Jan 2006 14:28:52 +0000
Subject: Give a few functions the inline attribute. (AD_pop_and_chdir): Use
 gotos to avoid some duplication. (AD_push): Rewrite an assertion so that the
 entire computation goes away when assertions are turned off.
