Right, that's still a reasonably straightforward solution for C... I
think what I'm more concerned about is C++, where templates break the
simple model of source to object to linking. Trying to wrap my head
around what the pipeline would look like in the C++ case.

I've got some ideas for automatic detection of bugs in C/C++ code,
looking into the feasibility of using Clang as a front-end in the hope
of only having to write a parser for the ASCII version of bitcode
(dead easy) instead of C (somewhat easy) and C++ (hard).
