There appears to be a bug in function matching rules using conversion
operators to convert class types to built-in types.

The following example fails:

class A
{
  public:
    operator const char * (void) { return "Hello"; }
    A() {}
    ~A() {}
};

main()
{
  A a;
  const char *cp = 1 + a;
  const char *cp2 = a + 1;
}

Output of compile:
