Do you mean DWARF-2 here?  If so, I completely agree.  It seems like
SOM has some named sections - at least we're managing to get objdump to
tell me there's a GDB_STRINGS section - so I don't know what the
problem is.

At one point in the past, the Compaq testdrive systems offered aCC.  I
don't think they do any more though.

Thanks for the response, Dave - if you don't think we need to hold on
to aCC support, then I doubt anyone else will either.  However, there's
no need to rush; I'll wait for at least a few weeks, in case anyone
else has comments, and then come back to this if no one does.

I'd be much happier working on support for GCC :-)  Especially if that
means DWARF-2 debug information!
