# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.

dnl Public macro.
dnl
dnl This macro emits shell code which does some
dnl very basic checks related with the availability
dnl of some commands and utilities needed to allow
dnl configure script bootstrapping itself when using
dnl these to figure out other settings. Also emits
dnl code that performs PATH_SEPARATOR auto-detection
dnl and sets its value unless it is already set with
dnl a non-empty value.
dnl
dnl These basic checks are intended to be placed and
dnl executed as early as possible in the resulting
dnl configure script, and as such these must be pure
dnl and portable shell code.
dnl
dnl This macro may be used directly, or indirectly
dnl when using other macros that AC_REQUIRE it such
dnl as XC_CHECK_PATH_SEPARATOR.
dnl
dnl Currently the mechanism used to ensure that this
dnl macro expands early enough in generated configure
dnl script is making it override autoconf and libtool
dnl PATH_SEPARATOR check.

dnl

dnl
dnl Strictly speaking the check is done in two steps. The
dnl first, which does the actual check, takes place in
dnl XC_CONFIGURE_PREAMBLE macro and happens very early in
dnl generated configure script. The second one shows and
dnl logs the result of the check into config.log at a later

dnl The funny name of this file is intentional in order to make it
dnl sort alphabetically after any libtool, autoconf or automake
dnl provided .m4 macro file that might get copied into this same
dnl subdirectory. This allows that macro (re)definitions from this
dnl file may override those provided in other files.
dnl Override an autoconf provided macro
dnl -------------------------------------------------
dnl This macro overrides the one provided by autoconf
dnl 2.58 or newer, and provides macro definition for
dnl autoconf 2.57 or older which lack it. This allows
dnl using libtool 2.2 or newer, which requires that
dnl this macro is used in configure.ac, with autoconf
dnl 2.57 or older.
