Would it be possible to add a diagnostic to GCC to warn when C++
keywords are being used as identifiers? Maybe also add any
objective C keywords too.

This seems like it would be useful to someone writing library
functions that could, at some later time, be imported (cut and paste)
into code for the other languages, as well as for code being converted
from C to C++.
