This is missing the synchronized_pool_resource and unsynchronized_pool_resource classes but is otherwise complete. This is a new implementation, not based on the existing code in <experimental/memory_resource>, but memory_resource and polymorphic_allocator ended up looking almost the same anyway. The constant_init kluge in src/c++17/memory_resource.cc is apparently due to Richard Smith and ensures that the objects are constructed during constant initialiation phase and not destroyed (because the constant_init destructor doesn't destroy the union member and the storage is not reused). * config/abi/pre/gnu.ver: Export new symbols. * configure: Regenerate. * include/Makefile.am: Add new <memory_resource> header. * include/Makefile.in: Regenerate. * include/precompiled/stdc++.h: Include <memory_resource> for C++17. * include/std/memory_resource: New header. (memory_resource, polymorphic_allocator, new_delete_resource) (null_memory_resource, set_default_resource, get_default_resource) (pool_options, monotonic_buffer_resource): Define. * src/Makefile.am: Add c++17 directory. * src/Makefile.in: Regenerate. * src/c++11/Makefile.am: Fix comment. * src/c++17/Makefile.am: Add makefile for new sub-directory. * src/c++17/Makefile.in: Generate. * src/c++17/memory_resource.cc: New.
