+# 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

+dnl separated list argument.
+dnl
+dnl Embedding only takes place when using automake 1.14

+dnl in generated configure script.
+dnl
+dnl distclean and maintainer-clean targets are modified
+dnl to avoid unconditional removal of dependency subdirs
+dnl which triggers distclean and maintainer-clean errors
+dnl when using automake 'subdir-objects' option along
+dnl with per-target objects and source files existing in
+dnl multiple subdirs used for different build targets.
+dnl
+dnl New behavior first removes each dependency tracking
+dnl file independently, and only removes each dependency
+dnl subdir when it finds out that it no longer holds any
+dnl dependency tracking file.
+dnl
+dnl When configure option --disable-dependency-tracking
+dnl is used no amending takes place given that there are
+dnl no dependency tracking files.

+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 Emits shell code that computes the path separator

+dnl
+dnl Non-empty user provided 'PATH_SEPARATOR' always

+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 configure stage. Placement of this second stage in
