Re: bug in autoconf 2.13, but where ? No bug with newer version

| Hi,
| I am on linux, redhat 7.3.
| I am trying to use automake/autoconf with pam_ssh. aclocal is aclocal-1.4,
| automake is automake-1.4 and autoconf is autoconf-2.13.
| Here are the commands and outputs:
| 
| $ aclocal
| $ automake -a -c
| automake: configure.in: installing `./install-sh'
| automake: configure.in: installing `./mkinstalldirs'
| automake: configure.in: installing `./missing'
| configure.in: 196: required file `./ltmain.sh' not found
| automake: Makefile.am: installing `./INSTALL'
| $ autoconf
| configure.in:98: warning: AC_TRY_RUN called without default to allow cross 
compiling
| configure.in:157: warning: AC_TRY_RUN called without default to allow cross 
compiling
| configure.in:195: warning: AC_TRY_RUN called without default to allow cross 
compiling
| autoconf: Undefined macros:
| ***BUG in Autoconf--please report*** AC_LIBOBJ
| configure.in:10:AC_SUBST(LIBTOOL_DEPS)
| configure.in:211:AC_FUNC_MALLOC
| configure.in:216:AC_CONFIG_FILES([Makefile])
| configure.in:217:AC_CONFIG_COMMANDS_PRE(
| configure.in:219:AC_SUBST(LTLIBOBJS)])
| configure.in:6:AC_CONFIG_SRCDIR([pam_ssh.c])
| 
| 
| 
| If I use aclocal-1.5, automake-1.5 and autoconf-2.53, I get for autoconf
| configure.in:218: error: do not use LIBOBJS directly, use AC_LIBOBJ (see 
section `AC_LIBOBJ vs. LIBOBJS'
| When I modify configure.in according to what I found in documentation,
| everything goes fine. 

So what is the problem?  Add AC_PREREQ(2.53) above AC_INIT.
