Well, you'd need more than just a parser, since you'd often have to pick
up on typedefs and other type information.

I wonder whether writing an alternate swig backend or something might
work.

I tried to use DL to wrap libc for MetaRuby but found that it is
lacking necessary features to make it 100% useable (like 64 bit
integers for stat(2)). Switching to DL2 adds an unfamiliar
dependency whereas RubyInline is a familiar dependency.
