View all issues with Tentatively Ready status.
The rebase on C++17 in P0996 had the effect of deleting the feature test macro __cpp_lib_experimental_memory_resource: the macro was ostensibly tied to the memory_resource facility that had become part of C++17, but we overlooked that there was a residual piece that has not been adopted in the IS, namely the resource_adaptor class template.It is still useful to be able to detect the presence of resource_adaptor, so we should reinstate the feature test macro and bump its value.
