|Subject:||gl_MANYWARN_ALL_GCC() leads to many spurious warnings|
|Date:||Fri, 6 Jul 2012 17:17:12 -0400|
The result is that, even after we explicitly disable dozens of them again, we still generally get a lot of spurious warnings when building with --enable-gcc-warnings. Furthermore, since that option also enables -Werror, Emacs generally does not build at all in this configuration (unless you monkey around with WERROR_CFLAGS).
Why not simply use "-W -Wall -Wextra" and perhaps a few others, plus a few overrides to turn off the warnings those enable that aren't useful with Emacs? That way, we'd only get warnings that had been reasonably well tested.
