5521 * include/bits/fs_path.h [!_GLIBCXX_USE_CXX11_ABI]: Remove special
5522 cases for old basic_string.
5523 * testsuite/21_strings/basic_string/cons/char/8.cc: Test
5524 allocator-extended constructors unconditionally. Add extra members to
5525 allocator type when using old string ABI.
5526 * testsuite/21_strings/basic_string/allocator/71964.cc: Enable test
5528 * testsuite/21_strings/basic_string/cons/wchar_t/8.cc: Likewise.

5531 -fno-inline added to test flags.
5533 * testsuite/21_strings/basic_string/requirements/
5534 explicit_instantiation/debug.cc: Remove XFAIL for old ABI.

5537 assertion failures with old std::string ABI.
5539 * include/bits/fs_path.h (path::_List::erase): Replace both overloads
5541 (path::pop_back(), path::_M_erase_from(const_iterator)): New member
5542 functions that will only erase elements at the end.
5543 * src/filesystem/std-path.cc (path::_List::_Impl::pop_back()): Define.
5544 (path::_List::_Impl::_M_erase_from(const_iterator)): Define.
5545 (path::_List::operator=(const _List&)): Use _M_erase_from(p) instead
5547 (path::_List::pop_back()): Define.
5548 (path::_List::_M_erase_from(const_iterator)): Define.
5549 (path::operator/=(const path&)): Use pop_back to remove last component
5550 and _M_erase_from to remove multiple components.
5551 (path::_M_append(basic_string_view<value_type>)): Likewise.
5552 (path::operator+=(const path&)): Likewise.
5553 (path::_M_concat(basic_string_view<value_type>)): Likewise.
5554 (path::remove_filename()): Likewise.
5555 (path::lexically_normal()): Use _List::_Impl iterators instead of
5556 path::iterator. Use pop_back to remove components from the end. Clear
5557 trailing filename, instead of using erase(const_iterator) to remove
5558 a non-final component.
5559 * testsuite/27_io/filesystem/path/generation/normal.cc: Test
5561 * testsuite/27_io/filesystem/path/generation/normal2.cc: New test.
