It'll see the old AC_DEFUN 20# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us 21# using a macro with the same name in our local m4/libtool.m4 it'll 22# pull the old libtool.m4 in (it doesn't see our shiny new m4_define 23# and doesn't know about Autoconf macros at all.) 24# 25# So we provide this file, which has a silly filename so it's always 26# included after everything else. This provides aclocal with the 27# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything 28# because those macros already exist, or will be overwritten later. 29# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 30# 31# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here. 32# Yes, that means every name once taken will need to remain here until 33# we give up compatibility with versions before 1.7, at which point 34# we need to keep only those names which we still refer to. 35 36# This is to help aclocal find these macros, as it can't see m4_define. 37AC_DEFUN([LTOBSOLETE_VERSION], [m4_if([1])]) 38 39m4_ifndef([AC_LIBTOOL_LINKER_OPTION], [AC_DEFUN([AC_LIBTOOL_LINKER_OPTION])]) 40m4_ifndef([AC_PROG_EGREP], [AC_DEFUN([AC_PROG_EGREP])])
