execute gnuplot from install directory for MinGW 64 bit build

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

I have tried to build gnuplot of vs source using gcc 4.8.2 from MinGW-w64 (64bit SEH).

Help file problem is overcome according the information by 
http://gnuplot.10905.n7.nabble.com/gnuplot-on-64-bit-Windows-again-td17580.html 

Here I write in more detail

1.Seaech hhctrl.ocx from the computer.
2.Using pexports (available from MinGW site), make def file,
 pexports hhctrl.ocx > hhctrl.def
3. Generate dll.a using dlltool
 dlltool -l hhctrl.dll.a -d hhctrl.def hhctrl.ocx
4. Change LDLIBS  in config/mingw/Makefile for example
 LDLIBS += /c/PROGRA~2/HELPWO~1/lib/hhctrl.dll.a 

*******************************************
I could execute gnuplot and wgnuplot on build directory ( config/mingw)
However, I cannot execute them because of Application Error. (0xc000007b).

If somebody knows the way to overcome this issue, please let me know.

Regards

Tatsuro
