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

[Patrice DUMAS - DOCT]

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.
