When compiled with gcc 4.1.0 on Linux, the program below causes the assembler
to issue an error complaining about foobar being defined twice. I believe the
program is well-formed and should compile and run successfully to completion
(it does with Intel C++ 10.0 on Linux).

$ cat x.cpp && gcc -dumpversion && gcc x.cpp
namespace N {
  extern "C" {
    extern const int foobar;
    const int foobar = 1;
    struct S { static const int foobar; };
    const int S::foobar = 2;
  }
}
int main () { return !(N::foobar + 1 == N::S::foobar); }

4.1.0

/tmp/ccL0oF3c.s:29: Error: symbol `foobar' is already defined

------- Comment #1 from pinskia at gcc dot gnu dot org  2007-10-15 18:31 -------
On the trunk, I get the following error:

t.cc:5: error: previous declaration of 'const int N::S::foobar' with 'C++'
linkage
t.cc:6: error: conflicts with new declaration with 'C' linkage

So fixed. This is the error message one would expect.
