conftest problem using autoconf 2.13-14

[Elisabetta Ronchieri]

Hi,

I am working on RH 7.2 and using the following autotool:

autoconf 2.13-14
automake 1.4p5-2
libtool 1.4-8

The autogen.sh script is reported below:

#! /bin/sh

set -x

if [ ! -d ./config ]; then
    mkdir ./config
fi

rm -f config.cache

aclocal -I config
touch NEWS README AUTHORS ChangeLog
libtoolize --ltdl --force --copy
autoheader
automake --foreign -a -c -i --add-missing
autoconf

During its execution I receive the following message:

./bootstrap
+ '[' '!' -d ./config ']'
+ mkdir ./config
+ rm -f config.cache
+ aclocal -I config
+ touch NEWS README AUTHORS ChangeLog
+ libtoolize --ltdl --force --copy
You should update your `aclocal.m4' by running aclocal.
Putting files in AC_CONFIG_AUX_DIR, `config'.
+ autoheader
+ automake --foreign -a -c -i --add-missing
automake: configure.in: installing `config/install-sh'
automake: configure.in: installing `config/mkinstalldirs'
automake: configure.in: installing `config/missing'
+ autoconf

Why is there the message: You should update your `aclocal.m4' by running
aclocal.??
How can I do to remove it??

The configure.in file is reported below:

During its execution I receive the following message:

At this point I find conftest, conftest.c and conftest.o files in my

a mistacke in doing what??
