Rather than using '.', use [a-zA-Z...] to limit the RNG to the same set
of characters as the C code (I'm not sure what the official set is,
though). I can understand rejecting a too-long name, but do we really
also want to reject a too-short name?

'make syntax-check' with 'cppi' installed will flag this for you.

Sorry, I can't help there. But I think we've pointed out enough issues
to warrant a v2 submission.
