What kind of new warnings does gcc 4.0 emit?

It should be checked whether the warnings are valid and should really be 
fixed.

A past example are the signed warnings pre-releases of gcc 3.3 
(including the pre-release a stable SuSE release shipped as compiler...) 
emitted with -Wall that were no longer emitted in the final gcc 3.3 
release.

Altogether, new warnings in gcc 4.0 might be a nice diagnostics for the 
people who are also trying to find bugs using -W, but I don't see urgent 
reasons for fixing them before gcc 4.0 is actually released.
