[Bug c++/15949] New: Error using a qualified-id in a function template

[apl at alum dot mit dot edu]

Using a pointer-to-member call referring to a virtual member function inside a
templated function results in the error: 


invalid use of ' NUNetRef::overlaps' to form a pointer-to-member-function.  Use
a qualified-id.


The example compiles in 3.3.3 and 3.4.0 but doesn't compile in 3.4-20040604.  If
I make the templated function a regular function, it compiles without error.

<example checked in momentarily>

If I change the collision function to not be templated ala

  bool collision (NUNetRef&a, NUNetRef& b) {
    int dummy;
    NUNetRefCompareFunction f = &NUNetRef::overlaps;

    return (a.*f)(b);
  }

Then it compiles without error.

This is a dup of bug 15875 which is fixed by reverting the patch which caused this regression.
