* This header is designed to be included multiple times. If any of the __need_
* macros are defined, then only that subset of interfaces are provided. This
* can be useful for POSIX headers that need to not expose all of stdarg.h, but
* need to use some of its interfaces. Otherwise this header provides all of
* the expected interfaces.
*
* When clang modules are enabled, this header is a textual header to support
* the multiple include behavior. As such, it doesn't directly declare anything
* so that it doesn't add duplicate declarations to all of its includers'
* modules.
