autom4te doesn't work over NFS under Linux 2.4

[H. J. Lu]

autom4te in autoconf 2.59 has

# Open the index for update, and lock it.  autom4te handles several
# files, but the index is the first and last file to be update, so
# locking it is sufficient.
$icache_file = new Autom4te::XFile $icache, O_RDWR|O_CREAT;
$icache_file->lock (LOCK_EX);

But flock interface doesn't work over NFS under Linux 2.4. Can it
use fcntl interface for file locking instead?
