Just use Symbolics C on a Symbolics or ZetaC on a TI Explorer. (ZetaC was recently put in the Public Domain by its author, so you can take a look at how it was implemented.) Both of them I believe implemented C89.
There’s also someone writing a C to Common Lisp translator that takes some of the same approaches as those compilers: <https://github.com/vsedach/Vacietis> Something like that would make it possible to pull C code into a project like Mezzano.
(Another approach would be to write an LLVM back-end that generates Common Lisp using the same approach as ZetaC, and port clang to it.)
