Aha.  I forgot to include system information:  apologies.  This is
the 'official' Snow Leopard version of ncurses, from a clean install of
OS X 10.6 on a MacBook Pro.  The /usr/include/ncurses.h
file includes the lines:

#ifndef NCURSES_OPAQUE
#define NCURSES_OPAQUE 1
#endif

and now that you mention it, I see that the macports version of
ncurses has a '#define NCURSES_OPAQUE 0' here instead.  I wonder
why Apple decided to do this.

Thank you.  That's very helpful.
