If Autoconf (or packages using it) engages a high warning level by default

I don't think anybody's advocating that. It'd be an option. The typical practice is for packages to have a build-time option like './configure --enable-gcc-warnings' which some developers use but most builders do not.

I am definitely supportive of that sort of approach. If it is implemented, then it should be in a consistent way.

Many free software developers are now using compilers other than GCC on a daily basis (e.g clang) so it would be good if the approach is not entirely GCC specific.
