It'll see the old AC_DEFUN 19# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us 20# using a macro with the same name in our local m4/libtool.m4 it'll 21# pull the old libtool.m4 in (it doesn't see our shiny new m4_define 22# and doesn't know about Autoconf macros at all.) 23# 24# So we provide this file, which has a silly filename so it's always 25# included after everything else. This provides aclocal with the 26# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything 27# because those macros already exist, or will be overwritten later. 28# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 29# 30# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here. 31# Yes, that means every name once taken will need to remain here until 32# we give up compatibility with versions before 1.7, at which point 33# we need to keep only those names which we still refer to. 34 35# This is to help aclocal find these macros, as it can't see m4_define. 36AC_DEFUN([LTOBSOLETE_VERSION], [m4_if([1])]) 37 38m4_ifndef([AC_LIBTOOL_LINKER_OPTION], [AC_DEFUN([AC_LIBTOOL_LINKER_OPTION])]) 39m4_ifndef([AC_PROG_EGREP], [AC_DEFUN([AC_PROG_EGREP])])
