Could the DJGPP (a.k.a. go32) target be one of those?

AFAICT DJGPP should be fine. The default debugging format for DJGPP
is still SDB isn't it? In that case the new DWARF CFI unwinder
wouldn't be used, unless DWARF2 EH info is generated.

The GCC config files seems to suggest that DJGPP also supports DWARF2.
If that indeed works, compiling with -gdwarf-2 would make the DWARF
CFI support kick in.

OTOH, GDB 6 will have many valuable fixes, and it would be a pity to
deny those features from users of platforms that could be broken by
the merge.

But for some, DWARF CFI support will be a valuable fix :-).

So how about waiting for 6.1 with the merge?

Hmm, having stuff slightly broken in 6.0 might be more acceptable to
our users than breaking things in 6.1.
