--- Comment #4 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
I would suggest that you implement this as a plugin. Plugins are particularly
useful for enforcing this type of coding standards. If you make a generally
useful plugin like one enforcing MISRA standards, it could be distributed with
GCC in order to serve as a testcase for the plugins framework.
