[Bug c++/26291] New: [3.4/4.0/4.1/4.2 regression] Invalid ellipsis in operator not diagnosed

[reichelt at gcc dot gnu dot org]

As some operator functions take a fixed (or at least limited) number
of arguments, an ellipsis is not allowed as argument for such operator
functions.
However, none of the following four cases is diagnosed since GCC 3.0:

===================================
struct A
{
    A& operator= (int, ...);
    A& operator[] (int, ...);
    A& operator++ (...);
    operator int(...);
};
===================================

All cases were diagnosed correctly in GCC 2.95.3 (although the compiler
would crash later). Therefore I'm rating this as a regression.
