   * @brief Historical synonym for `<sysconf.h>`.
   *
   * This file used to contain the declarations of sysconf and its associated constants.
   * No standard mentions a `<sys/sysconf.h>`, but there are enough users in vendor (and
   * potential NDK users) to warrant not breaking source compatibility.
   *
   * New code should use `<sysconf.h>` directly.
