[Bug c++/14024] g++ isn't reporting aliasing warnings

This example is from PR 16111:
#include <stdio.h>

float foo ()
{
  unsigned int MASK = 0x80000000;
  return (float &) MASK;
}

int main() {
  printf ("%f\n", foo());
  return 0;
}

'g++ -Wstrict-aliasing' does not generate a warning about breaking
strict-aliasing rules. When '(float&)MASK' is replaced with equivalent '*(float
*)&MASK', 'gcc -Wstrict-aliasing' produces expected warning.
