Maybe your use pattern, i.e. Emacs in CVS and old GDB, is somewhat unusual.  I
would expect most users to have released versions of both programs, probably
those which are included in their distribution.

I expect GDB 7.0 to be released before Emacs 23.2 in which case it's likely
that when 23.2 is bundled with a distribution that will include 7.0 too.  I'm
more concerned about the quality of the mode being worthy for inclusion in the

In any case, at the moment we're talking about bleeding edge Emacs in CVS.
I'm not sure it's reasonable to expect such a version to be stable enough to
debug itself and it would seem more natural to use a release version for such
a purpose.

I don't think that requiring 7.0 will make gdb-mode useless but, in truth, I
don't know who uses it, or how they use it.  I guess that would need a poll
and even then those that repond are likely to be unrepresentative.

I think that to swap back now that Emacs 23.1 has been released will only
cause confusion.

No, but hopefully they will read the documentation.  If not, then all is
pretty much lost anyway.
