./configure --help prints:

  --enable-gtk-doc        use gtk-doc to build documentation [[default=no]]
  --with-graphite2=[yes/no/auto]
                          Use the graphite2 library [default=no]

./configure --disable-gtk-doc prints:

Additional shapers (the more the better):
        Graphite2:              false

Other features:
        Documentation:          yes

If more additional shapers the better, why isn't it tried to enable graphite2 by default?

My logic says, that when --disable-gtk-doc is provided, at the end "Documentation: no" shall be printed.

The first warning is harmless, see #402 and #424. We don’t want Graphite by default as it introduces extra dependency, feel free to enable it if you want. The last one looks like a bug, patches are welcome of course.
