Maybe it's would be best to put all related patches in a single place
to avoid need to collect then from mailing list (otherwise it's very simple to 
forget some of them)

Currently I have put in suggestion Mark sent recently:

#undef DBX_REGISTER_NUMBER
#define DBX_REGISTER_NUMBER(n) \
  ((write_symbols == DWARF2_DEBUG) ? svr4_dbx_register_map[n] : dbx_register_map[n])

But I don't have any objections to leave things as they were (without this
addition)

One more problem: 

It seems that -gcoff support have suffered from too serious bitrot:
	trying to run LAPACK tests with this gcc version run into trouble
	when GAS (binutils-2.11.2 and also some other recent versions) 
	failed when -g was specified (with -gstabs+ all was Ok)

I verified that I have the same problem with gcc-3.0 binaries
