The program is *ONE* module, 256K worth of source code.  4 UNIX compilers
have no problem with it. I have no more compilation problems with Lattice
after using the -r0 -b0 switches, EXCEPT that Lattice generates BAD code
(BBS.S with odd address). The point I am trying to make is that neither
of the two C compilers on the Amiga come even close to the ones on UNIX.
I don't want to start "kludgin the code", just because the compiler is
BROKEN. I'll just go back to UNIX.
