Using -Werror by default is a very bad idea. Warnings can have false
positives, or otherwise be harmless. And in particular, different compiler
versions can trigger different warnings: false positives get fixed, but new
warnings get added. So using -Werror makes you very dependent on the
compiler version. And really, a warning is not an error for a reason.
It makes sense to use -Werror-* for some specific warnings, e.g.
-Werror-implicit-function-declaration in C, but a blanket -Werror in shipped
tarballs is a very bad idea.
