- 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.
-
- This patch was authored by Thorsten Glaser <tg at mirbsd.de>
- with copyright assignment to the FSF in effect.

-I talked to Andrew about what files he changed in GCC and created and

-files in glibc but I don't see any use of '.section .note.GNU-stack' in
-any assembly files in glibc (for any platform) so I wasn't planning on

+ 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.
+
+ This patch was authored by Thorsten Glaser <tg at mirbsd.de>
+ with copyright assignment to the FSF in effect.

+I talked to Andrew about what files he changed in GCC and created and
+tested this new patch. Andrew also mentioned changing some assembly
+files in glibc but I don't see any use of '.section .note.GNU-stack' in
+any assembly files in glibc (for any platform) so I wasn't planning on
+creating a glibc to add them to mips glibc assembly language files.
+
+OK to check in this patch?
