No longer working on this. If someone to take my patch and update it and also
update the testsuite, that is ok with me.

Leaving as P2; as stated in the audit trail, this problem has the potential to
seriously confuse people.

The patch from comment #14 is not really useful as it f.i. warns for
int sink;
void bar()
{
int j;
sink = j;
}
t.c: In function 'bar':
t.c:5: warning: 'j' is used uninitialized in this function
t.c:4: note: 'j' was declared here

Created an attachment (id=12131)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=12131&action=view)
This patch checks if the warning location is within cfun.
I probably won't find CPU cycles to test this properly in the near future.

------- Comment #27 from kazu at gcc dot gnu dot org 2006-08-28 17:28 -------
The real fix it to issue "uninitialized warnings" before the inliner kicks in
but after we go into SSA, which is impossible until we start doing early SSA.
As Nathan suggests, this caveat should be mentioned in the release notes.

I have no recollection of writing any patch about this (and have no objection

A backport bootstraps and regtests ok on the 4.1 branch. Don't know if the
side-effects of this patch makes it appplicable for backporting though.
