This topic has been beaten many times, but in short, compiler warnings
are not portable and are often bogus and/or subjective. Even within the
same compiler line, one version may not generate a warning and the next
one will, for the same code. Requesting the compiler to fail in these
conditions is counter-productive and hostile towards users.

As a user, I have to deal with a number of libraries used in my
projects. Some of these libraries enforce -Werror. And almost always
this causes problems for me because, of course, compilation fails
because of warnings on the target platforms I use. Some libraries are
generous enough to allow me disable warnings-as-errors. Others I have to
patch and then maintain the patches myself. The best case scenario is
the build passes because it doesn't emit warnings and I don't have to do
anything, but even then -Werror doesn't give me anything, as a user.
