Libc++ tried accomodating systems that need to be able to define various __need_FOO macros before including C library headers, however it does not appear to be needed anymore in most cases. Indeed, glibc used to use that system to conditionally provide definitions, however almost all instances of these macros have been removed from glibc years ago. I think the next step would be to also fix Clang's own builtin headers to stop needing these macros. Differential Revision: https://reviews.llvm.org/D131425
