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 The original code implemented AC_CHECK_HEADERS_ONCE and AC_CHECK_FUNCS_ONCE
|
|
dnl in terms of AC_DEFUN and AC_REQUIRE. This implementation uses diversions to
|
|
dnl named sections DEFAULTS and INIT_PREPARE in order to check all requested
|
|
dnl headers at once, thus reducing the size of 'configure'. It is known to work
|
|
dnl with autoconf 2.57..2.62 at least . The 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. But note that autoconf's implementation of
|
|
dnl AC_CHECK_DECLS_ONCE expects a comma-separated list of symbols as first
|
|
dnl argument!
