[PATCH] D157793: [Headers] Add missing __need_ macros to stdarg.h

[James Y Knight via Phabricator via cfe-commits]

jyknight added a comment.

I'm a bit confused by this change vs its description.

It looks like stdarg already supported `__need___va_list`, which is what you said Apple needs. Does Apple //also// require the other __need_va_copy/etc, too? If not, why add support for them? (I think we should prefer not to add support for pieces that are not actually needed)
