Ah OK. I believe the problem is this in lib/init/mke_mapset.c:

/* give the mapset a default window for the entire location */
         sprintf(buffer,"cat '%s'/PERMANENT/DEFAULT_WIND  > '%s'/'%s'/WIND",
                 location, location, mapset) ;
         system(buffer) ;

but at the minute my mind has gone blank as to the portable way to replace 
that. I general audit of calls to system() would have caught that if we're 
able to get round to doing it I suppose.
