Follow-up Comment #1:
> For example, grep does not support -e , but egrep does.
AC_PROG_GREP looks for a grep that does support -e, so a configure script that
uses that should have a $GREP that works, assuming you have one somewhere in
your $PATH. (If not, you'll need to get one.)
> This lack of support of -e makes the configure script fail, although there
is a usable egrep.
Autoconf's 'configure' script doesn't use 'grep -e' anywhere that I can see.
Are you debugging some other 'configure' script that uses 'grep -e'? If so,it
should use AC_PROG_GREP and "$GREP -e" and you should have a grep in your
$PATH that works.
