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.

Something in there about how "gdba" and "gdb" differs would be great!

Thanks a lot for your quick and insightful comments!
