gis.m is a pure Tcl/Tk application (rather than hybrid C & Tcl/Tk), so
it will use the "wish" executable specified by $GRASS_WISH (or
whichever one comes first in the path), regardless of which configure
switches are used.

The native Windows NVIZ (using the standard Tcl/Tk distribution
compiled from source) sort of works. However, exec commands hang, so
the map browser currently doesn't work. I'm not entirely sure why;
executing the same commands in a vanilla "wish" shell works fine.
