We use it for running latex (i.e., looking for some warning messages
in the latex output to know if we need to run it again). This could
be coded around and/or removed entirely if desired.
However, I notice that libtool makes extensive use of egrep.
Specifically, even if I remove AC_PROG_EGREP, it's checked for later
in configure and is used a lot by libtool.
I'd be surprised if there's a system out there that doesn't have some
flavor of egrep that satisfies AC_PROG_EGREP (especially if Libtool
uses it heavily). Do we know if this is the case, or is this a
hypothetical that a suitable egrep might not be found?
