+dnl This file is free software, distributed under the terms of the GNU
+dnl General Public License.  As a special exception to the GNU General
+dnl Public License, this file may be distributed as part of a program
+dnl that contains a configuration script generated by Autoconf, under
+dnl the same distribution terms as the rest of that program.
+
+dnl This file defines some "once only" variants of standard autoconf macros.
+dnl   AC_CHECK_HEADERS_ONCE          like  AC_CHECK_HEADERS
+dnl   AC_CHECK_FUNCS_ONCE            like  AC_CHECK_FUNCS
+dnl   AC_CHECK_DECLS_ONCE            like  AC_CHECK_DECLS
+dnl   AC_REQUIRE([AC_FUNC_STRCOLL])  like  AC_FUNC_STRCOLL
+dnl The advantage is that the check for each of the headers/functions/decls
+dnl will be put only once into the 'configure' file. It keeps the size of
+dnl the 'configure' file down, and avoids redundant output when 'configure'
+dnl is run.
+dnl The drawback is that the checks cannot be conditionalized. If you write
+dnl   if some_condition; then gl_CHECK_HEADERS(stdlib.h); fi
+dnl inside an AC_DEFUNed function, the gl_CHECK_HEADERS macro call expands to
+dnl empty, and the check will be inserted before the body of the AC_DEFUNed
+dnl function.
+
+dnl This is like onceonly.m4, except that it uses diversions to named sections
+dnl DEFAULTS and INIT_PREPARE in order to check all requested headers at once,
+dnl thus reducing the size of 'configure'. Works with autoconf-2.57. The
+dnl size reduction is ca. 9%.
+
+dnl Autoconf version 2.59 plus gnulib is required; this file is not needed
+dnl with Autoconf 2.60 or greater.
