Huh? You need to read the pthread spec at least once. Cygwin's default pthread mutex type is RECURSIVE. And the pthread mutex attribute calls will reject any 'normal' or 'errorchecking' mutex type requests. It's fully in the pthread spec is this regard. If your application is assuming that the default mutex type is non recursive, it is a bug in your code.
