From 92b499acff8a35d64ec0f9b27b5df06209656ca9 Mon Sep 17 00:00:00 2001
From: Corinna Vinschen <corinna@vinschen.de>
Date: Mon, 10 Oct 2011 14:57:48 +0000
Subject: 	* Align usage output, version output, as well as usage and
 version 	option handling to use the same style throughout all Cygwin
 utils. 	Throughout use program_invocation_short_name to refer to
 current 	process name in Cygwin executables. 	* utils.sgml: Align
 documentation to above change.  Add missing 	sections for getconf, ldd, and
 setmetamode. 	* strace.cc (proc_child): Avoid compiler warning.
