[Bug c++/14618] New: Cannot compile test_thread.cpp from boost

[schmid at snake dot iap dot physik dot tu-darmstadt dot de]

The following code s.C, reduced from the original file libs/thread/test/
test_thread.cpp included in current boost repository, is rejected by gcc 3.4, 
but accepted by gcc 3.3. I have not investigated but given the error messages I 
guess this problem is also responsible for the failure of the libs/python/test/
embedding.cpp test. This looks like a regression to me. 
 
source code s.C  
 
namespace boost { 
class noncopyable 
{ 
 protected: 
    noncopyable() {} 
    ~noncopyable() {} 
 private: 
    noncopyable( const noncopyable& ); 
    const noncopyable& operator=( const noncopyable& ); 
}; 
 
 
class thread : private noncopyable 
{ 
public: 
    bool operator==(const thread& other) const; 
}; 
} // namespace boost 
 
 
void comparison_thread(boost::thread* parent) 
{ 
    boost::thread thrd; 
    if (thrd == boost::thread()) ; 
}
