And here's another update.  A recent change in Gforth resulted in more
code, and we now have reverted that change:

   instr. bytes  system
    28    103    Gforth AMD64
    16     44    iforth 5.0.27 (plus 20 bytes entry and return code)
     7     19    lxf 1.6-982-823 32-bit
    32    127    SwiftForth 4.0.0-RC89 (calls LSPACE)
    26     92    VFX Forth 64 5.11 RC2
