- # serial 4 lt~obsolete.m4
- # 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.
