What is the version of autoconf that is needed for compiling maxima?
I've been using autoconf 2.5 and that works fine. But on a Solaris box,
the default version of grep doesn't understand -e, which breaks the
build of the info files.
I'd like to add an autoconf check to find a version of grep that
understands -e, but that needs AC_PROG_GREP, which doesn't seem to be
available in 2.50.
