Petr,

I've build gnuplot with the current sources and with your patch applied.

Terminal type set to 'x11'
gnuplot> plot sin(x)
gnuplot> gplt_x11.c:1528: SENDING MY WINDOWID TO GNUPLOT...
mouse.c:1854: set current_x11_windowid to 12345

When I try a "show all" I do not see any variables that look like GPVAL_TERM_WINDOWID. In fact, I don't see any variables beginning with "GPVAL_...". 

I'm obvioulsy missing something.
