PiperOrigin-RevId: 277767054 -- 018f3b040df51d91a988fa146fee163721e605e9 by Abseil Team : Change libstdc++ lacking std::unique_ptr check from a gcc version check to based on feature macros. PiperOrigin-RevId: 277736042 -- 475844775ae343e2414318f08549ee3fa6676a8d by CJ Johnson : Pass allocator_type through allocator_traits before extracting the typedefs PiperOrigin-RevId: 277730393 -- d843bc4bc30bf5b11af76db8beda8634b6111a62 by Abseil Team : Convert the Waiter::Init() method to the default constructor and define a destructor for the Waiter class. Use placement new and delete with Waiter objects. PiperOrigin-RevId: 277728823 -- 1ba6edf421dd2dfe13c55970a03c99592cb6677d by Derek Mauro : Use lowercase spelling for include of dbghelp.h When cross-compiling under MinGW this is important PiperOrigin-RevId: 277629783 -- cfc662a6fa357a84ddda8037156c7f26cee40c36 by Abseil Team : Don't use atomic ops on waiter and wakeup counts in WIN32 waiter mode. Port the new CONDVAR waiter mode code in CL 277366017 to the WIN32 waiter mode. PiperOrigin-RevId: 277603611 -- 833106542e61fa0832900adf3c1b2afc6890b94b by Abseil Team : Add the PerThreadSem::Destroy() method. For ABSL_WAITER_MODE_CONDVAR or ABSL_WAITER_MODE_SEM, PerThreadSem::Destroy() is used to destroy the pthread mutex and condition variable or the POSIX semaphore.
