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:
