+Subject: [PATCH] Allow -Werror and -Werror=* through flag filtering
+
+* build-aux/ltmain.in (func_mode_link): allow -Werror and -Werror=* through
+  flat filtering at link time.
+
+  This is needed for detecting likely-runtime problems with LTO using
+  e.g. -Werror=odr or -Werror=lto-type-mismatch.
