23.0.0; Failure to ./configure despite recent makeinfo

[Gerhard]

Hi, 

I downloaded emacs-unicode-2 with 

cvs -z3 -d:pserver:address@hidden:/cvsroot/emacs co
-remacs-unicode-2 emacs

On configuring (with "./configure --prefix=/usr --with-gtk
--enable-font-backend --with-xft"), I get the following:

but a "makeinfo --version" gives

"makeinfo (GNU texinfo) 4.11"

I guess the error is in "configure.in"

___________________________________________________

if test "$MAKEINFO" != "no" && \
  test x"`$MAKEINFO --version 2> /dev/null | $EGREP
'texinfo[[^0-9]]*([[5-9]]|4\.[[6-9]])'`" = x; then
                              ^^^^^
   MAKEINFO=no    
fi
