The other option is to abandon SWIG in favour of Python's ctypes
module. This is more work, but it's also more flexible, and will
produce a better result in the end.
It may even be possible to automate the wrapper generation. While this
won't be perfect, neither is SWIG; any automatic approach has the
problem that a C prototype doesn't contain enough information.
