windows binaries in which gd-jpeg libraries bug are fixed

[Tatsuro M. <tma...@ya...>]

Hello

There has been a bug report:

****************************************
#1643 jpeg terminal broken in windows binaries

https://sourceforge.net/p/gnuplot/bugs/1643/


The bug comes from gd and jpeg libraries were created in inconsistent way.
I found the origin of inconsistency and create fixed gd and jpeg libraries.
(jpeg library is changed from jpeg-9a to libjpeg-turbo-1.4.1)

The fixed binaries are available at
http://www.tatsuromatsuoka.com/gnuplot/Eng/winbin/

> From here, inquiry to the developers.

I think it is better re-create windows gnuplot-5.0.1 binaries.
(Also a user pointed out help file lacks figures for 5.0.1)

For 4.6 version, 4.6.6 binaries have gd-jpeg library bugs.
I think it will be better 4.6.7 windows binaries because it is the last version of gnuplot ver. 4.6.
