This will allow std::mutex and std::lock_guard to be used elsewhere in the library without pulling in the whole of <chrono>. Previously the whole of <bits/std_mutex.h> was conditional on the _GLIBCXX_USE_C99_STDINT_TR1 macro, but only the std::unique_lock members that use <chrono> facilities should depend on that. std::mutex only needs to depend on _GLIBCXX_HAS_GTHREADS and std::lock_guard can be defined unconditionally. Some parts of <bits/std_mutex.h> and <mutex> are based on code in <ext/concurrence.h> which dates from 2003. However, the std::unique_lock implementation was added in 2008 by r135007, without using any earlier code. Therefore the new header file has copyright years 2008-2018. * include/Makefile.am: Add new <bits/unique_lock.h> header. * include/Makefile.in: Regenerate. * include/bits/std_mutex.h [!_GLIBCXX_USE_C99_STDINT_TR1] (mutex) (lock_guard): Define independent of _GLIBCXX_USE_C99_STDINT_TR1. (unique_lock): Move definition to ... * include/bits/unique_lock.h: New header. [!_GLIBCXX_USE_C99_STDINT_TR1] (unique_lock): Define unconditionally. [_GLIBCXX_USE_C99_STDINT_TR1] (unique_lock(mutex_type&, time_point)) (unique_lock(mutex_type&, duration), unique_lock::try_lock_until) (unique_lock::try_lock_for): Define only when <chrono> is usable. * include/std/condition_variable: Include <bits/unique_lock.h>. * include/std/mutex: Likewise.
