Libtool distributed with apache does not work properly on AIX

           Summary: Libtool distributed with apache does not work properly
                    on AIX
           Product: Apache httpd-2.0
           Version: 2.0.49
          Platform: Other
        OS/Version: AIX
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: Build
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: krist.vanbesien@bit.admin.ch


I wanted to build mod_jk2 on AIX. The normal build process uses the libtool
distributed with apache. This libtool does not work on our system. The reason
seems to be a bug in libtool, which is triggerd by the fact that we keep apache
sources, binaries and docroots on different filesystem. 

Under certain circumstances libtool tries to create a lockfile by creating a
hard link to from itself to the working directory:

    if test "$need_locks" = yes; then
      until $run ln "$0" "$lockfile" 2>/dev/null; do
        $show "Waiting for  $lockfile to be removed"
        sleep 2
      done

ln as it is called in libtool does not work across filesystems though. The
problem is worsened by the fact that libtool is often called with the --silent
option, and that ln's output is sent to /dev/null. So the user never gets to
find out what is going on...

I replaced the "ln" with "$LN_S" in libtool, and this allowed me to compile the
module without any problem.
