    I guess that if we manage to make CONFIG to work, IDLOCS will be a piece
of cake!

    What is the problem with this? When I read the sources I saw that when
directive.c was about to emit a configuration byte, it acquired the byte
from the coff_xxxx functions and then it emitted the data. This in fact
happens twice (as I can remember) one the first and on the second pass. So
memory is initialized and marked as allocated. There is no problem if
configuration directives are spread in the source (or am I wrong?!!!!)

    That's another good idea. The only problem is that I do not know yet
much about coff and the rest. So it would be very difficult for to cope with
it. I'll try later this week to see what can I do.
    No, I do not need it now, I just wanted to see why gpasm complaints when
I compile programs with SDCC and I thought it would be a good test (for me)
to fix the problem. Do not bother if you wouldn't anyway.
