Re: Change of cvs at 2007-08-31 Ethan Merritt only for x11 but not for win

Hi Ethan

cc. Prof. Kakuto, HBB

Now I think the reply at the end of this now is doubtful.  Prof. Kakuto does maintain the wgnuplot
binaries frequently.

Prof. Kakuto!  Am I right?

I have build a CVS gnuplot on cygwin for cygwin octave at Jan 18, 2008.
However 
gnuplot> show version

        G N U P L O T
        Version 4.3 patchlevel 0
        last modified June 2007
        System: CYGWIN_NT-5.1 1.5.25(0.156/4/2)

With this cvs gnuplot on the cygwin, the mouse zooming in 2D and rotating 3D plots by mouse was
possible from the octave plotting even if the plotings via pipe were done from not only the
cygwin-octave but also the mingw-octave.

I think the binary at 
http://www.ring.gr.jp/pub/text/TeX/ptex-win32/utils/

is not so old.  
The incorrect date was perhaps a bug in version related codes in the cvs source trees and it may have
been fixed quite recently.

Anyway the mouse zooming problem was not solved in the pgnuplot+wgnuplot on windows if the most recent
pgnuplot+wgnuplot.

As you said in your reply, it was no problem for linux+wine, there may be something windows specific
problem.

Hi, Hans!!
I think you are the main develpper for the wgnuplot.
Are there any suggestions to me?
