I am trying to get GDB 4.7 to work on Ultrix 4.2a/4.3 with the object files
produced by the DEC C++ compiler.

I have already made several fixes to prevent GDB from crashing when it
sees symbol types that it wasn't expecting, and I'm trying now to get
it to understand DEC/MIPS' extensions to COFF format to store C++ symbol
information (e.g. Classes, references, etc.).

1) Is there anyone else currently working on GDB on MIPS/Ultrix that may have
a more recent version of "mipsread.c" that I should be changing?

2) What should I do about changes that need to be made to "symconst.h" to
#define the new symbol types, etc.?  The Ultrix version of that file
doesn't have them either at this point.

3) We have also found that when you link a REALLY BIG program on Ultrix,
the loader can end up mangling the symbol table information because it is
not expecting that any program might have more than 32767 symbols.  I have
some fixes for this problem as well (allowing GDB to read the mangled
symbol tables as if they were OK), but they are rather ugly.  What should I
do with them?

Basically, is there anyone else there I should be talking to?
