 Just for the sake of completeness:
 gcc issues an error if you just try to compile "int x=x;".
 
 You get no error/warning, if you try to compile the code inside a
 function, ie. "void foo() { int x=x; }".
 But that's not a gcc extension, just a missing warning about the use of
 an uninitialized variable.
