Se the `local' arg of ad-hook.

Ah I see. [ Reminds me that I'd like to add property lists to processes. ]
But in this particular case, I guess the best approach is to merge
gdb-reset into gud-reset so the sentinel doesn't have to care about the
difference between various gud-minor-mode.
BTW: the regexp "^\*.+*$" in gdb-reset should probably be "\\`\\*.+\\*\\'"
[ or even thrown away and replaced with something like a buffer-local variable
`gud-auxiliary-buffer' which would be set to non-nil (better yet: to the
main *gud* buffer) in those *foo* buffers. ]

Sure. Except I'd add the hook buffer-locally so you don't need to check
(eq (current-buffer) gud-comint-buffer).
