libstdc++-v3/ChangeLog:
* include/bits/alloc_traits.h (allocate): Add [[maybe_unused]]
attribute.
* include/bits/regex_executor.tcc: Remove name of unused
parameter.
* include/bits/shared_ptr_atomic.h (atomic_is_lock_free):
Likewise.
* include/bits/stl_uninitialized.h: Likewise.
* include/bits/streambuf_iterator.h (operator==): Likewise.
* include/bits/uses_allocator.h: Likewise.
* include/c_global/cmath (isfinite, isinf, isnan): Likewise.
* include/std/chrono (zoned_time): Likewise.
* include/std/future (__future_base::_S_allocate_result):
Likewise.
(packaged_task): Likewise.
* include/std/optional (_Optional_payload_base): Likewise.
* include/std/scoped_allocator (__inner_type_impl): Likewise.
* include/std/tuple (_Tuple_impl): Likewise.
