[Bug c/16330] New: Unions handled incorrectly with -fshort-enums

[miko at stacken dot kth dot se]

The following code correctly prints 1 when compiled without -fshort-enums, but 
incorrectly prints a 0 when compiled with -fshort-enums. I assume this is an
endian problem as it works correctly on a i686-pc-linux-gnu target.


#include <stdio.h>

enum E { a, b };

union Y
{
  int x;
  enum E   y;
  void* z;
};

int main()
{
  union Y un;
  un.x=1;
  printf("%d\n", un.y);
}
