adam@0 12 # These exist entirely to fool aclocal when bootstrapping libtool.
adam@0 13 #
adam@0 14 # In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
adam@0 15 # which have later been changed to m4_define as they aren't part of the
adam@0 16 # exported API, or moved to Autoconf or Automake where they belong.
adam@0 17 #
adam@0 18 # The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
adam@0 19 # in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
adam@0 20 # using a macro with the same name in our local m4/libtool.m4 it'll
adam@0 21 # pull the old libtool.m4 in (it doesn't see our shiny new m4_define
adam@0 22 # and doesn't know about Autoconf macros at all.)
adam@0 23 #
adam@0 24 # So we provide this file, which has a silly filename so it's always
adam@0 25 # included after everything else. This provides aclocal with the
adam@0 26 # AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
adam@0 27 # because those macros already exist, or will be overwritten later.
adam@0 28 # We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
adam@0 29 #
adam@0 30 # Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
adam@0 31 # Yes, that means every name once taken will need to remain here until
adam@0 32 # we give up compatibility with versions before 1.7, at which point
adam@0 33 # we need to keep only those names which we still refer to.
adam@0 34
adam@0 35 # This is to help aclocal find these macros, as it can't see m4_define.
