Re: test suite problem

Hi Bruno,

I assume you are using Autoconf 2.72? I don't see an easy way to fix
this and Autoconf is trivial to install so it is probably just worth
mentioning in the README.

The gnulib-cache.m4 are actual differences that need to be fixed.

>From autoconf/NEWS for version 2.72:

*** All internal uses of AC_EGREP_CPP and AC_EGREP_HEADER have been removed.

$ /usr/bin/automake --version
automake (GNU automake) 1.16.5

This doesn't seem to cause any issues from what I can tell, but
Automake is easy enough to install as well.
