That's my understanding, too. Furthermore, the compiler warnings are
presumably there to help the developer decide if he needs to use "require".
In the case of tooltip.el, the undefind functions from gud and gdb-ui can only
be invoked by using their debugger modes, so, AFAIK, "require" is not needed
for these features. To use (require 'feature) just to eliminate warnings,
would be the wrong thing to do, I think.
