Hello, everyone:

Current CVS gcc has an option "-feliminate-dwarf2-dups" that
generates dwarf2 debug info containing references across compilation
units, which current gdb seems to be unable to parse.  I wrote a
quick-and-dirty patch (against 20040103 snapshot) to make it work.

The patch isn't really clean (in particular it contains a known memory
leak as indicated by the FIXME), and I don't really expect it to be
included.  However, I think this patch *might* be useful to someone,
since "-feliminate-dwarf2-dups" seems to reduce debug info size
significantly for large projects (the effect is more clear when the
DW* symbols for DWARF-2 relocation are deleted), which may be helpful
to distributors making debug-info packages.  Maybe some of you may
tell me some way to improve the patch, as well as to make it
accessible to those needing similar functionality.

Hopefully you'll CC me since I'm not subscribed.
