There are some more header files whose existence gnulib has been assuming for
years. You could apply the same change for them:

  <ctype.h>
  <errno.h>
  <fcntl.h>  - need to adjust lib/flock.c
  <locale.h> - need to adjust m4/regex.m4, lib/regex_internal.h
  <signal.h>
  <stdio.h>
  <stdlib.h>
  <string.h> - need to adjust tests/test-argp.c
  <time.h>
