I've been hacking at this for a few days with no progress, and I'm out
of things to try.
Can anyone offer suggestions? Should I be building with GPASM and
GPLINK? Is it likely that the libsdcc.lib is the wrong one? If someone
could try to do a build, I'll zip the directory and post it to the list,
if that would make it easier. I'd zip a beer in there too, if I could!
