[Pyrex] External declarations and GCC-XML?

At some point there may be a tool to semi-automate the conversion
of C to Pyrex declarations. It seems unlikely that this will
ever be fully automated, however, because there isn't enough
information in a C header file for Pyrex to find out everything
it needs to know.

I know of one person who started working on a tool like this,
but I haven't heard what sort of progress he's made recently.

Actually, that's the least of the difficulties -- if syntax were
the only issue, it would almost be trivial. The real problems
mostly concern what to do about #defines, #ifdefs, etc...
