>Description:
Neither N::x' nor 'N::y' should be mangled in the example
below but 'N::x' does get mangled.  The work-around is to use
the variable in a non-inline function as is done with 'N::y'.

This example works in 2.95.2, because the namespace is never
mangled by 2.95.2.
>How-To-Repeat:
Compile the following code:

extern "C" {
  namespace N { extern int x,y;}
}

int N::x = 42; // I'm incorrectly mangled

int f() { return N::y; }

int N::y = 43; // I'm correctly not mangled
