  gl_CHECK_NEXT_HEADERS implies AC_CHECK_HEADERS_ONCE
  
  * m4/include_next.m4 (gl_CHECK_HEXT_HEADERS): Document this.
  * m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): Don't bother to invoke
  AC_CHECK_HEADERS_ONCE on a header that we also invoke
  gl_CHECK_NEXT_HEADERS on, since the latter invokes the former.
  * m4/netdb_h.m4 (gl_HEADER_NETDB): Likewise.
  * m4/pthread.m4 (gl_PTHREAD_CHECK): Likewise.
  * m4/sched_h.m4 (gl_SCHED_H): Likewise.
