I believe this is valid C++:

extern "C++" struct S { static int x; } s;

g++ 4.2.4, 4.3.1, and the Debian version of 4.3.2 reject the declaration with
the error:

static.cpp:1: error: invalid use of ‘static’ in linkage specification

I don't think static members of structures were intended to be disallowed by
the prohibition duplicate storage classes in declarations like

extern "lang" static int x;

This seems to fix the problem:
