We meta-compiled 64 bit Gforth on the 32 bit Gforth, too, because there was, 
once upon a time, no 64 bit machine.  Even the 32 bit Forth system 
(bigForth) that created the first Gforth images was once metacompiled from a 
16 bit system.

Yes, but wrangling with 8 registers on a RAFTS-like compiler seems to be a 
waste of time, at least IMHO.
