[Bug c/26632] New: spurious warning: value computed is not used


Using gcc 4.1.0 on amd64, with -Wall (64 bit target):

int g(void);
long h(void);
void f(void)
{
        0 ? h() : g();
}

foo.c:6: warning: value computed is not used

Either changing 0 to 1 or swapping g and h makes the warning go away.
This was the result of a (very reasonable) macro expansion.
