I just tried the explicit -Wuninitialized, very good, 
and I noticed at least its documented in the man pages.

But who ever uses -Wuninitialized ?

People expect to get -Wuninitialized with -Wall, everyone
uses -Wall, it would be great if any expectable warnings are
disabled you should get the same warning message.

So to recap, it would be much more usefull if I got this
message when compiling with -Wall but no -O :

cc1: warning: -Wuninitialized is not supported without -O

This would make sence because to specify -Wall, *is* to explicitly
mention -Wuninitialized.
