I can't remember why XTL insists on using long long -- the documentation

The extern "C" prototyping just before the class is ignored by cxx then.
It's annoying but I don't know if it's just a quirk of gcc or required by
the standard -- probably one of those aspects that are left to the
compiler writers.
