[Bug c++/31157] New: Bitfield is not promoted

["ismail at pardus dot org dot tr" <gcc-bugzilla at gcc dot gnu dot org>]

Following testcase compiles fine with gcc 3.4.6 but not with gcc 4.2.0 20070307
:

----- cut here -----
#include <iostream>

using namespace std;

class Foo
{
    public:
        Foo() { x=1; y=0; };
        unsigned int x:12;
        unsigned int y;
};

int main()
{
  Foo bar;

  max(bar.y,bar.x);

  return 0;
}
----- cut here -----

The error is :

max.cpp: In function 'int main()':
max.cpp:17: error: no matching function for call to 'max(unsigned int&, short
unsigned int:12&)'
