Even if "-i=mi" doesn't work for you "--annotate" is not the answer.  The mode
in 23.1.50 really needs GDB 7.0, which han't been released yet!  There used to
be two GDB releases per year but the last was back in March of last year.  It's
hard to co-ordinate changes but the aim is for it to be released shortly.

Yes I can see that this with GDB 7.0 - so that's another bug.  Thanks for the
report.

This is related to old GDB.  Emacs enquires if it can run these versions of
GDB in non-stop mode but can't prevent the display of the resultant error
message because it is duplicated in the console output, which goes to the GUD
buffer.

Hmm, I don't know but if you can get GDB 7.0 most (but not all) of these 
problems
will clear up.  If you need to use GDB in earnest it's probably best to use the
released Emacs 23.1 which uses "--annotate".  However, if you have some time,
then I appreciate bug reports for Emacs 23.1.50.  Ultimately this latter mode
will be much better than the current one but it depends on users making bug
reports because I don't use it that often now.
