right at the end of running configure, on the warnings section (about not
having gnuplot installed etc), if someone does not have gnuplot installed,
there's an extra line that simply says "yes".

configure: WARNING: building documentation disabled because gnuplot was not
found; make dist will fail
configure: WARNING: yes
configure: WARNING: 
configure: WARNING: I didn't find gnuplot.  Plotting commands will use the
configure: WARNING: native graphics toolkit.

This does not occur on the stable branch. I have tracked this down to the
revision 8a84849ad986 and prepared a changeset. Please pull the revision
c753ee228708 from https://bitbucket.org/carandraug/octave

Also, not a bug but on the list of libraries (at the end of the configure
output), while some say "libraries" others simply say "LIBS". I have made this
consistent. Please pull the revision a25937adede9 from the same place.

I have also found that the multiline warning messages on m4/acinclude.m4 only
have "configure: WARNING" on the first line (the others have one per line (the
ones at the end of configure.ac). These warns are first stored in warn_thing
variable and then passed to OCTAVE_CONFIGURE_WARNING(). Should I replace it by
something like

OCTAVE_CONFIGURE_WARNING([gnuplot not found. It isn't necessary to have
gnuplot installed, but])
OCTAVE_CONFIGURE_WARNING([without native graphics or gnuplot you won't be able
to use any of])
OCTAVE_CONFIGURE_WARNING([Octave's plotting commands.])

? I don't see the warn variables being used anymore but if they exist to know
that we have already warned about it, They could maybe be replaced by
warn_thing=yes ? I can prepare a changeset for this.
