MinGW std::thread fix

I talked earlier about a basic fix for MinGW enabling the use of std::thread and friends in MinGW. Since I will probably use them a lot, I wrote a small header file which does the work for you. It is available on github as a gist : https://gist.github.com/1154023

Since I believe people are too lazy to click links, and also because I want my blog to appear to have a lot of code in it, you will also find it just below:

/* Only use the code below if we have GCC with no support for GNU
 * threads 
 */
#if !defined(_GLIBCXX_HAS_GTHREADS) && defined(__GNUG__)

/* The boost thread library is used as a replacement for the
 * standard thread library. We'll consider it to be fully 
 * compatible with the missing library. See http://www.open-std.org/
 * ...jtc1/sc22/wg21/docs/papers/2008/n2497.html
 */

#include <boost/thread/thread.hpp>
#include <boost/thread/mutex.hpp>
#include <boost/thread/recursive_mutex.hpp>
#include <boost/thread/locks.hpp>
#include <boost/thread/condition_variable.hpp>

/* Only classes are copied. Use boost directly or a real standard
 * library if you want free functions.
 */

namespace std {
  using boost::thread;
  
  using boost::mutex;
  using boost::timed_mutex;
  using boost::recursive_mutex;
  using boost::recursive_timed_mutex;
  
  using boost::lock_guard;
  using boost::unique_lock;
  
  using boost::condition_variable;
  using boost::condition_variable_any;
}

#endif /* Crippled GCC */
