The way in which r.in.gdal does it is a hack:

        G__put_window( &def_wind, "../PERMANENT", "DEFAULT_WIND" );

Actually, G__put_window itself is something of a hack, as it
encourages individual modules to contain hardcoded assumptions about
the directory structure.

I suggest that a more correct way to do it would be to temporarily
switch the mapset to PERMANENT, then use:

	G__put_window (window,"", "DEFAULT_WIND");

Also, it's arguable that r.in.gdal should be modifying the per-mapset
window rather than the default window; a normal user may not have the
necessary permissions to modify anything in PERMANENT.
