Interesting to note: Wine is being run through cppcheck after every
two-weekly release as well. It's showing up occasional bugs and
questionable coding in wine, but mostly bugs in cppcheck ;-)

I suggest running the whole server code base through cppcheck, seeing
what it comes up with then going through very carefully to work out
what's a bug in Xorg code and what's actually a bug in cppcheck.
Probably a lot of the latter still.

That said, it has usefully spotted bad stuff in wine. Just very
noisily. It'll probably manage at least as well on a codebase as large
and old as X11.
