Sorry, ignore all that, turns out my code was working with an older
version of Lua. That's a real shame, having some sort of portable
support for C-function coroutines would be useful :(

Thanks for the report.
Is this by deliberate design? Or by virtue
of
the fact that it hasn't been deliberately implemented? As far as I can
gather the lua_resume function works by re-using the function pointer
on the top of the stack from the previous call, so it's possible (in 5.1.4 at least) to yield C functions
so long as you ensure that this value is maintained. You also have to
handle the resume logic yourself since there's only one entry point:
