gcc-python-plugin is a plugin for GCC 4.6 onwards which embeds the
CPython interpreter within GCC, allowing you to write new compiler

comes with cpychecker: a tool for static analysis tool of CPython
extensions.

After a hiatus, I've restarted work on an API for GCC plugins -

BTW, how many other GCC plugins are written in C?
It's still a work-in-progress, but can be seen here:

I'm working on a GCC plugin which performs static analysis of Python
extension code [1]
In various places I need access to a VAR_DECL for various globals from C
code, many of which potentially aren't used directly within the
compilation unit. For example, I may need to reference this global:

It ships with gcc-with-cpychecker, which implements static analysis
