I'm terribly sorry -- compiling with optimisation is so slow that I
normally don't do it (only once in a while and before releases) and
without optimisations gcc doesn't report things like these.

Yes, run->type can only ever be of one of the CRT_* values, so we could
alternatively just turn any of the other `case's into `default'.
