jhc supports both cpp and m4 as preprocessors, use the '-fcpp' or '-fm4'
options to enable them. I can pretty easily add support for the LANGUAGE
pragma if that helps.

The library format is not quite a cabal file, but rather just a subset.
ideally ones build system (such as autoconf, or cabal-install, or cook,
or whatever) would examine the current system and spit out an
appropriate one to invoke jhc on. In the meantime, it is easy enough to
modify a cabal file into a form jhc can grok until tools learn to cope.
