Err, USE_COLOR is defined in curses.c.  If you're asking whether or not
it's available in standard curses, here's what I got from the
man page:

  PORTABILITY
    All these functions are supported in the XSI Curses standard,
    Issue  4.  The  standard  defined the dedicated type for
    highlights, attr_t, which is not defined in SVr4 curses. The
    functions  taking attr_t  arguments are not supported under SVr4.

Anyway, I think I see where you're going with this line of questions, so
I went ahead and redid the patch so Curses::Window#color_set only exists
if USE_COLOR is defined.

Patch is attached.
