console mode gnuplot for windows with wxt doen not work (gnuplot 4.3 / mingw)

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

Hello

I have posted a thread about a problem on console mode gnuplot for windows with wxt.
I am using GCC-4.4.0/Mingw. 

The gnuplot.exe (ver 4.3 ) with does not start.

$ gnuplot

Tatsu@INSPIRON6000 /c/Program Files/Gnuplot4.3wxt
$

Without wxt
$ gnuplot


        G N U P L O T
        Version 4.3 patchlevel 0

However, 
$ gnuplot -e "plot sin(x); pause 1"
and
$ echo 'plot sin(x) ; pause 1'  | gnuplot

works even on gnuplot with wxt.

I have struggled with gdb and found that

(!isatty(fileno(stdin))) is false for the gnuplot without the wxt but true for one without wxt.
I also found taht stdin, stdout, and stderr does not work.

In short,  gnuplot with wxt built on gcc/mingw does not have standard i/o.

Perhaps this may be a side effect with gnuplot linked with wxWedgets.

Michael Goffioul had built the console mode of gnuplot for windows with wxt by MSVC++.

This problem may be specific to the combination of GCC/mingw and wxt.

Does anyone have ideas on this issue ?
