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

What you are suggesting is the fmrst 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
(relativel} slow) and a big switch with an integer selector (which is what
C Forth 83 uses).
