>Description:
The demangler can't demangle anonymous namespaces that
are contained in other namespaces.  E.g. given

namespace C {
  namespace {
    int cX;
  }
}

you might get a mangled name like

_Q21C27_GLOBAL_.N.fum__Q23AAA3inAi.cX

if you compile this with GCC 2.95.3.  And the demangler
can't demangle that.

It can demangle top-level anonymous namespaces:

namespace {
  int X;
}

demangles to {anonymous}::X.  (I wish it were
(anonymous namespace)::X, as in V3; that's another matter).

Of course, GCC 2.95.3 didn't support namespaces 
all that well to begin with.
