Thank you for doing this! One thing I'm wondering about, is that I'm pretty sure clang also allows at least some of these to be used with plain C as well, for example for things like the old use of "auto" in C conflicting with the newer C++11 meaning of "auto". Would it be possible to do likewise for GCC as well? Just an idea.
I think that would belong in -Wc++-compat and would need changes to the C front end, which I'm almost entirely unfamiliar with. My patch doesn't add any new diagnostics, it just makes slight adjustments to existing ones. If you want new diagnostics in the C front end you'll need to convince a C FE maintainer. That would be too far outside my comfort zone :-)
