Re: The primary Mingw Octave 2.9.13 binary test

[Tatsuro MATSUOKA]

Dear Michael

Thanks a lot ! Plot was successful owing to your advise!!

The snapshot is

The gnuplot was used your binary setting 
gnuplot_binary("C:/programs/octave-2.9.13/bin/pgnuplot")
in octaverc.  Excuse me to use your wgnuplot without your
permission. 

Mkoctfile does not now work well, this will be perhaps
come from path problem.

However, this mingw octave seems much stabler the previous
binary mingw 2.9.4.  Perhaps this is due to the code has
been revised.

I think now is a good chance to challege to make mingw
octave.   Because those who is not expert could built it. 
 
I propose to use GnuWin32 which recudes the difficulty.

I hope more people challange the mingw building.
