No you are thinking wrong, it will be the same warning as it is uninitialized,
the flag just turns on the
warnings for those cases.

Yes, I did expect a different warning, because
int i = i;
would be uninitialized use and self initialization.
And because of an special warnings flag I expected it to be different from the
uninitialized use w

I can't reproduce this with either gcc-3.4.4 or 4.0.0 on mingw
The example gives the warning
warning: 'i' might be used uninitialized in this function
iff I add -Winit-self
That is consistent

strange...I just tried it again with this example:
extern void foo(int);
int main()
{
int i = i;
foo(i);
return i;
}
And I get only this (C and C++ front-end / -O1, -O2 and -O3):
$ gcc
