tty build warning

Browse Source 
Use casts to try to suppress a couple of assignments of long to short
that Michael's compiler warns about.  'cw->maxrow' might have a value
that's too big for 'short' (when dealing with really big menus), but
'cw->maxcol' never will (unless someone comes up with a terminal or
emulator that's wider that 32K-1 characters...).
