M-x gdba assumes that GDB is being run with the "--annotate=3" option. M-x gdb
filters the output to determine whether GDB is being run with "--fullname" or
"--annotate=3". The former gives the old Emacs 21 functionality (or lack of
it!) and is worth using if all else fails.
As someone read somewhere that --annotate=3 should be used with
Emacs22, that's what we're using with Emacs22. So if all "gdb" (sans
"a") does it trying to figure that out, "gdba" is what we should and
will use.
So they do indeed do the same thing, in most cases, when "--annotate=3" is
used (the default). There is a problem when GDB commands like "run" are
included in GDB scripts because these get run _before_ GDB commands that Emacs
uses to set up the mode. Perhaps I'll add a note in the manual.
Something in there about how "gdba" and "gdb" differs would be great!
Thanks a lot for your quick and insightful comments!
