   to save space, or it can be set to something longer to store both a
   character and some attributes.  By default they do not define CHTYPE,
   and when CHTYPE is not defined, the default type is "unsigned long" instead
   of the traditional "char".  However, SVR4 <curses.h> does define
   _VR3_COMPAT_CODE, so we can use that to detect when we should use the SVR4
   default if CHTYPE is not defined.  For other systems, just default to the
