  * m4/include_next.m4 (gl_INCLUDE_NEXT): Define and AC_SUBST
  INCLUDE_NEXT.
  (gl_CHECK_NEXT_HEADERS): New macro.
  * m4/fcntl_h.m4 (gl_FCNTL_H): use gl_CHECK_NEXT_HEADERS instead of
  the obsolescent gl_ABSOLUTE_HEADER.
  * m4/float_h.m4 (gl_FLOAT_H): Likewise.
  * m4/inttypes.m4 (gl_INTTYPES_H): Likewise.

  * m4/wctype.m4 (gl_WCTYPE_H): Likewise.
  * m4/inttypes.m4 (gl_INTTYPES_H): Define
  _GL_JUST_INCLUDE_SYSTEM_INTTYPES_H to avoid the problem of unclean
  builds, since ABSOLUTE_INTTYPES_H is no longer being defined.
  * m4/stdint.m4 (gl_STDINT_H): Likewise, for
  _GL_JUST_INCLUDE_SYSTEM_STDINT_H.
  * lib/fcntl_.h: Use @INCLUDE_NEXT@ @NEXT_foo_H@
  rather than @HAVE_INCLUDE_NEXT@ and @ABSOLUTE_foo_H@.
