The following program should not compile:

extern int foo;
static union
{
 int foo; // clash
};

C++ standard clause 9.5/2 states that members of anonymous unions must have
names distinct from other names in the same scope.

If the `extern' keyword is removed from the example above, the error is
diagnosed correctly (followed by an ICE).
