Latest trunk gives a set but not used warning for the following code:
int
foo (int status)
{
if signed char) __extension__ ({ union { __typeof(status) __in; int
__i; } __u; __u.__in = (status); __u.__i; }))) 0x7f) + 1) 1) 0))
return 0;
else
return 1;
}
It's a reduced test case from bootstraping gcc failure on Ubuntu 9.04.
