-commit 99368862e44740ff4fd33760893f04e14f9dbdf1
-Author: Felix Fietkau <nbd@openwrt.org>
-Date:   Tue Jul 31 00:52:27 2007 +0000
-
-    Port the mbsd_multi patch from freewrt, which adds -fhonour-copts. This will emit warnings in packages that don't use our target cflags properly
-    
-    SVN-Revision: 8256
-
-       This patch brings over a feature from MirBSD:
-       * -fhonour-copts
-         If this option is not given, it's warned (depending
-         on environment variables). This is to catch errors
-         of misbuilt packages which override CFLAGS themselves.
-
-       This patch was authored by Thorsten Glaser <tg at mirbsd.de>
-       with copyright assignment to the FSF in effect.
