+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_HEADER_STDC])  like  AC_HEADER_STDC
+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 Autoconf version 2.57 or newer is recommended.
