It'll see the old AC_DEFUN 206a46240fSmrg# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us 216a46240fSmrg# using a macro with the same name in our local m4/libtool.m4 it'll 226a46240fSmrg# pull the old libtool.m4 in (it doesn't see our shiny new m4_define 236a46240fSmrg# and doesn't know about Autoconf macros at all.) 246a46240fSmrg# 256a46240fSmrg# So we provide this file, which has a silly filename so it's always 266a46240fSmrg# included after everything else. This provides aclocal with the 276a46240fSmrg# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything 286a46240fSmrg# because those macros already exist, or will be overwritten later. 296a46240fSmrg# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 306a46240fSmrg# 316a46240fSmrg# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here. 326a46240fSmrg# Yes, that means every name once taken will need to remain here until 336a46240fSmrg# we give up compatibility with versions before 1.7, at which point 346a46240fSmrg# we need to keep only those names
