Re: [PATCH] bootstrap: check for AC_PROG_LIBTOOL as well as AM_PROG_LIBTOOL

Hi Jim,

Solaris 9 'grep' does not support the '-E' option. This is documented in the
autoconf manual:

     Traditional `grep' implementations (e.g., Solaris) do not support
     the `-E' or `-F' options.  To work around these problems, invoke
     `AC_PROG_EGREP' and then use `$EGREP', and similarly for
     `AC_PROG_FGREP' and `$FGREP'.

In a script like this, where you cannot rely on AC_PROG_EGREP either, I would
just grep configure.ac twice, with two different basic regular expressions.
