Minimal example

Missing braces in namespace declaration errors are currently being displayed
after a long chain of "non-errors". For namespaces in header files the
situation is even worse: arriving at the -ferror-limit is very easy. See
minimal example below.

3 Files: a.h, b.h, main.cpp (dependency on boost/any)

FILE: a.h:
#ifndef A_H_
#define A_H_
#include <iostream>
namespace test {
// } // uncomment this line to fix the error
#endif

FILE: b.h:
#ifndef B_H_
#define B_H_
#include <boost/any.hpp>
// uncomment this line to see how the "real error" is displayed:
#include <unordered_map>
#endif

FILE: main.cpp:
#include "a.h"
#include "b.h"
int main() { return 0; }
