Personally, warnings do not bother me as long as they aren't too many
(some packages evidently cannot be compiled without warnings without
investing a lot of effort in restructuring the code).

What does annoy me in the CVS is that apparently "make recompile" in
the lisp subdirectory doesn't DTRT for CC Mode, as afterwards I get
warnings about version mismatch between different cc-*.elc files quite
frequently.  ("make bootstrap" solves that, but I don't like to
bootstrap unnecessarily.)  I find myself in the need to manually
compile some of the cc-*.el files, which isn't easy, since the warning
message doesn't give any useful hints as to the files that need to be
recompiled.

FWIW, Eshell solves similar problems nicely, although it's possible
that CC Mode is more complex.
