I'd say we should only add -Wall if -Werror is not used, because if -Werror
is used, usually the package Makefiles play games with enabling and
disabling some warnings. For this we could use specs file as suggested by
Roland earlier:
%rename cc1 cc1rhorig
*cc1: %{!Wall:%{!Werror:-Wall}} %(cc1rhorig)
and use -specs=/usr/lib/rpm/redhat/specs in %{optflags}.
Some warnings like -Wpointer-sign are quite questionable and hit insane
amount of code...
