[boost] [filesystem] status() semantics?

To nail down the semantics of status(), let's try a different approach. 
Some of the difficulty may be a matter of miscommunication, so perhaps 
actual code will add clarity.

Perhaps Peter or others who have views on what the semantics of 
boost::filesystem::status() should be could change the code below to 
implement those semantics. Hopefully that will eliminate any confusion as 
to exactly meaning.

status_flag status_imp( const char * path, system_error_type * ec )
{
    struct stat path_stat;

    if ( ::stat( path, &path_stat ) != 0 )
    {
       if ( ec != 0 ) *ec = errno;
       return ((errno == ENOENT) || (errno == ENOTDIR))
          ? fs::not_found_flag : fs::error_flag;
    }

    system_error_type result(0);

    if ( S_ISDIR( path_stat.st_mode ) ) result |= fs::directory_flag;
    if ( S_ISREG( path_stat.st_mode ) ) result |= fs::file_flag;

    return result;
}
