My concern is that the dependency on -Wextra makes building glibc with
stock configure flags even more difficult than it is today. -Wextra
seems to be some sort of dumping ground for things that aren't ready yet
for -Wall for various reasons, and most of the GCC developers I talk to
regularly strongly recommend not use -Wall -Werror (like we do). -Wall
-Wextra -Werror would be worse.
