  Gnulib module: stdlib-h, system-posix
  @mindex stdlib-h
  @mindex system-posix
  
  Portability problems fixed by the Gnulib module @code{stdlib-h}:
  @itemize
  @item
  The macros @code{EXIT_SUCCESS} and @code{EXIT_FAILURE} are not defined on
  some platforms.
  @item
  Some platforms provide a @code{NULL} macro that cannot be used in arbitrary
  expressions:
  NetBSD 5.0
  @item
  Using the macro @code{MB_CUR_MAX} causes link errors on some platforms:
  Android NDK r16.
  @item
  The value of @code{MB_CUR_MAX} is too small (3 instead of 4) in UTF-8 locales
  on some platforms:
  Solaris 10.
  @end itemize
  
  Portability problems fixed by the Gnulib module @code{system-posix}:
  @itemize
  @item
  The macros @code{WIFSIGNALED}, @code{WIFEXITED}, @code{WIFSTOPPED},
  @code{WTERMSIG}, @code{WEXITSTATUS}, @code{WNOHANG}, @code{WUNTRACED},
  @code{WSTOPSIG} are not defined in this header file (only in
  @code{<sys/wait.h>}) on some platforms:
  MirBSD 10.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  The definition of the type @code{once_flag}, of the macro
  @code{ONCE_FLAG_INIT}, and the declaration of the function
  @code{call_once}, that are required by ISO C 23, are not provided.
  @mindex call_once
  To get them, import Gnulib module @code{call_once} and include
  @code{<threads.h>} rather than @code{<stdlib.h>}.
  @item
  System status macros such as @code{WEXITSTATUS} require an lvalue
  argument on some platforms.
  macOS 11.1.
  @end itemize
