+
+	This patch brings over a few features 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.
+	* -Werror-maybe-reset
+	  Has the effect of -Wno-error if GCC_NO_WERROR is
+	  set and not '0', a no-operation otherwise. This is
+	  to be able to use -Werror in "make" but prevent
+	  GNU autoconf generated configure scripts from
+	  freaking out.
+	* Make -fno-strict-aliasing and -fno-delete-null-pointer-checks
+	  the default for -O2/-Os, because they trigger gcc bugs
+	  and can delete code with security implications.
+
+	This patch was authored by Thorsten Glaser <tg at mirbsd.de>
+	with copyright assignment to the FSF in effect.
