If these are quite specific coding rules, wouldn't this be something ideal for 
a plugin rather than implemented in the compiler proper?

One can implement warnings with plugins (in python if desired!)

http://gcc-python-plugin.readthedocs.org/en/latest/basics.html#generating-custom-errors-and-warnings

Compiler plugins that implement specific coding rules are quite common, alas, 
using clang not GCC: https://wiki.documentfoundation.org/Development/Clang_plugins

It would be more generally useful to extend GCC to fully support this type of 
plugins.
