Octave-gui build fails for MinGW on current gui branch source

[Tatsuro MATSUOKA]

Hello

Due to very recent change octave-gui source, I could not build octave-gui on 
MinGW.

*****************************

Unlike the Ubuntu, there is not 'qterminal' directory in gui directory for the 
Windows.
What should I do to avoid the error from qterminal related things on the 
Windows?
