+Subject: [PATCH 1/1] disable -Werror in the coreboot build system
+
+we don't want it in libreboot, a coreboot distro.
+
+you have NO IDEA how many times users have complained
+in the past that libreboot doesn't build, and it was
+code that was actually fine in practice, but the compiler
+was just being overly pedantic. i often sit there and
+fix each one. no more.
+
+just remove Werror. this shall be libreboot policy from now
+on. it makes sense for coreboot  to enable this, because that
+is for developers. coreboot-distro is for coreboot users.
