Autoconf & grep 2.4.2

[John Poltorak]

I'm trying to rebuild the configure script for grep 2.4.2, but autoconf 
fails for some reason.

How do I tell what is wrong?


I did run aclocal and automake before hand but it doesn't make any 
difference. 


Here's a log of some of the msgs, but it means nothing to me:-

configure.in:11: your implementation of AM_INIT_AUTOMAKE comes from an
configure.in:11: old Automake version.  You should recreate aclocal.m4
configure.in:11: with aclocal and run automake again.
