gcc-3.2.3 does not issue warnings on "int a = a + 1"

[Remo Inverardi]

g++-3.2.3 on Debian SID does not issue warning when compiling the 
following code:

void foo()
{
   int xyz = xyz + 1;
}

The variable xyz is not defined at global scope, so a warning like 
"accessing uninitialized variable" would be appropriate.
