It'll see the old AC_DEFUN 20dfe7682dSmrg# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us 21dfe7682dSmrg# using a macro with the same name in our local m4/libtool.m4 it'll 22dfe7682dSmrg# pull the old libtool.m4 in (it doesn't see our shiny new m4_define 23dfe7682dSmrg# and doesn't know about Autoconf macros at all.) 24dfe7682dSmrg# 25dfe7682dSmrg# So we provide this file, which has a silly filename so it's always 26dfe7682dSmrg# included after everything else. This provides aclocal with the 27dfe7682dSmrg# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything 28dfe7682dSmrg# because those macros already exist, or will be overwritten later. 29dfe7682dSmrg# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 30dfe7682dSmrg# 31dfe7682dSmrg# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here. 32dfe7682dSmrg# Yes, that means every name once taken will need to remain here until 33dfe7682dSmrg# we give up compatibility with versions before 1.7, at which point 34dfe7682dSmrg# we need to keep only those names which we still refer to. 35dfe7682dSmrg 36dfe7682dSmrg# This is to help aclocal find these macros, as it can't see m4_define. 37dfe7682dSmrgAC_DEFUN([LTOBSOLETE_VERSION], [m4_if([1])]) 38dfe7682dSmrg
