If gud and gdb-ui are always going to be loaded whenever they have to
be (even after possible code changes in tooltip.el), then I believe
that the best way to avoid warnings is:

(eval-when-compile (require 'feature))

Otherwise, you can use things like `(if (fboundp 'myfun) ...)' or, if
necessary, `with-no-warnings'.  That would avoid silencing future
legitimate warnings. 

Sincerely,
