-Wall generates too many false positives in practice.  Perhaps some 
variant would be better, but we'd have to see the details.

I doubt whether all developers will agree about this, so it'll be useful 
to have an option that can be set in configure.ac. Packages whose 
developers like the commonly-used './configure --enable-gcc-warnings' 
approach could specify in configure.ac that warnings are off by 
default.  Packages whose developers like basic warnings (whatever they 
are) enabled by default could do that too.
