usually.  That's because the A_xxx and COLOR_PAIR(n) all fit into one
memory location.

But if you build ncurses configured for extended colors, (which none 
of the packagers have done - so far), you can define color pair values 
that do not fit into this mask. That would be with terminal descriptions 
such as xterm-88color or xterm-256color.

On the other hand, it's supposed to work for color pairs that
fit: the extended colors library copies the values to/from the
places they're used.
