Hi David,

Yes even if Frama-C's main goal is to develop semantic analysers, you 
can use the framework to encode most of the syntactic coding rules 
available in lint like tools.
Your plugin would be a very good starting point for anyone trying to 
implement its custom syntactic rules.
Thanks for showing it in public.

Your code seems correct. You should probably mention in the header the 
targetet version of Frama-C. Your plugin works with the unreleased 
Lithium-20081001+alpha1 version.

Besides the documentation generated in doc/html/index.html from the 
headers, you have the developer and architecture manuals 
(frama-c-architecture.pdf and plugin-dev.pdf).
Good entry points are db.mli, cil.mli and cil_types.mli.
We will try to improve this generated documentation.
