This release seems to be completely broken under Irix 6.  I compiled
with CC='cc -n32' under Irix 6.2 and gdb cannot even selftest:

% ./gdb gdb                                               irix6/gdb

This GDB was configured as "mips-sgi-irix6"...
cu_header: length=45061 abbrev_offset=52206, dwarf_abbrev_size=84256

Dwarf Error:  bad length in compilation unit header.

Setting up the environment for debugging gdb.
.gdbinit:5: Error in sourced command file:
No symbol table is loaded.  Use the "file" command.
(gdb) 

The extra msg was from a debug line I added:

*** dwarf2read.c.~1~    Tue Dec  2 15:59:34 1997
--- dwarf2read.c        Wed Dec  3 11:47:34 1997
*************** dwarf2_build_psymtabs_hard (objfile, sec
*** 940,943 ****
--- 940,944 ----
        if (cu_header.length > dwarf_abbrev_size - cu_header.abbrev_offset)
        {
+         printf ("\ncu_header: length=%d abbrev_offset=%d, dwarf_abbrev_size=%d", cu_header.length, cu_header.abbrev_offset, dwarf_abbrev_size);
          error ("Dwarf Error:  bad length in compilation unit header.");
          return;

So what's the problem here?  84256-52206 = 32050 and 45061 > 32050!
