Win32 build of gnuplot 5.0.2

[Bastian M. <bma...@we...>]

Hi,

you can find a binary build of gnuplot 5.0.2 for Windows using Mingw32 at
http://sourceforge.net/projects/gnuplot/files/gnuplot/5.0%20release%20candidates/
The installer and the zip package have both been downloaded around 90 
times so far (without an announcement).

My build environment etc. differs quite a bit from the previous builds 
done by Tatsuro Matsuoka. In particular my libraries are older and I do 
not have Mingw64 installed, so I cannot provide 64bit builds.

Feedback from testers would be greatly appreciated before moving this to 
the 5.0.2 release directory.
