I was thinking that the default C mode for gcc was C99, but now i've
discovered that it is really a mix of C90 and C99. This default mode
annoys me... but you are totally right here, this bug should be closed.
Can you believe that two persons were looking with gdb and were doing
some more weird and deeper tests, and none of us thought into simply
activating the warnings? :-)
