From: Zack Weinberg
Subject: [PATCH 3/3] Use AC_CHECK_HEADERS_ONCE for the tests done by AC_INCLUDES_DEFAULT.
Date: Fri, 6 Sep 2013 22:10:57 -0400

 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): Divide into a public
   macro that AC_REQUIREs _AC_INCLUDES_DEFAULT_REQUIREMENTS, and ...
   (_AC_CHECK_HEADERS_ONCE): ... a private macro, that doesn't.
   (_AC_HEADERS_EXPANSION): Use $ac_includes_default, not AC_INCLUDES_DEFAULT.
   (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Use AC_CHECK_HEADERS_ONCE.
   (all of the above): Sprinkle dnl's around.
