This seems wrong, and the diagnostics could be nicer (see gcc):
--
void f0() {
  // FIXME: Diagnose this?
  int g6;
  extern int g6;
}

void f1() {
  // FIXME: Diagnose this?
  int g7;
  __private_extern__ int g7;
}

void f2() {
  extern int g8; // expected-note{{previous definition}}
  // FIXME: Improve this diagnostic.
  int g8; // expected-error{{redefinition of 'g8'}}
}

void f3() {
  __private_extern__ int g9; // expected-note{{previous definition}}
  // FIXME: Improve this diagnostic.
  int g9; // expected-error{{redefinition of 'g9'}}
}
