Michael,

  Well, I've already re-invented this wheel: I have modified the
assembler/linker in the SDCC projest to support the '390 (the code is
checked into the sdcc project at www.sourceforge.net if you want to
see it; it's not yet in any released version of sdcc). I also have the
compiler working (*); it generates valid though definitely non-optimal
'390 24-bit code (if I can figure out how to get the compiler to use
dual DPTRs, it'll be a whole lot better).

  I'd like to see the .zip, though, to compare the implementation. I
had to do some interesting hacking, including mods to the .rel file
format, to get this working. Maybe "bill" came up with a better
solution...

        Peace,
                Kevin

(*) this is all untested on real hardware; if Dallas doesn't get my
TINI to me soon, my head will explode...
