GCC 4.x regression, for x >= 5:

$ cat > foo.c
unsigned foo(void)
{
#ifdef CONST
  const
#endif
  unsigned i = sizeof(unsigned) << 3;
  unsigned x = 1000;
  return x >> i;
}
^D
$ gcc-4.5.0 -O -S foo.c -DCONST
$ gcc-4.4.6 -O -S foo.c -DCONST
foo.c: In function 'foo':
foo.c:8: warning: right shift count >= width of type

g++ works.
