Sorry, you lose.  It can't be done in portable C.  Labels don't have
visible addresses.  Their scope is entirely contained within the enclosing
subroutine.

What you are suggesting is the first thing that I thought of doing when
I was writing C Forth 83, but I had to give up on that implementation
strategy.  The two options that I know of are indirect subroutine calls
(relatively slow) and a big switch with an integer selector (which is what
C Forth 83 uses).
