This doesn't actually change anything for the freestanding build, so is effectively a no-op. _GLIBCXX_HOSTED is always defined to 1 when these headers are included. However, somebody else is working on installing the additional headers for freestanding, so this is a prerequisite for that. -- >8 -- This adds checks for _GLIBCXX_HOSTED to a number of headers which are not currently installed for freestanding, but need to be for P1642R11 support. For example, needs to be installed for C++23 freestanding mode, but without stream iterators and streambuf iterators. Similarly, needs to be installed, but without std::allocator and std::shared_ptr. This change disables the non-freestanding parts of those headers. libstdc++-v3/ChangeLog: PR libstdc++/106953 * include/backward/auto_ptr.h [!_GLIBCXX_HOSTED]: Do not define shared_ptr members. * include/bits/alloc_traits.h [!_GLIBCXX_HOSTED]: Do not declare std::allocator_traits> specializations for freestanding. * include/bits/memoryfwd.h [!_GLIBCXX_HOSTED] (allocator): Do not declare for freestanding. * include/bits/stl_algo.h [!_GLIBCXX_HOSTED] (stable_partition): Do not define for freestanding.
