Also, add the functions :
use_default_colors();
assume_default_colors(fore, back);
(from ncurses) that allow the terminal default colours or user-specified
default colours to be used.
* Added code to __restartwin to restore meta and cursor visibility states
* Added code to __stopwin to disable meta.
* Added the *line group of functions for drawing character lines.
(this is a requirement of SUSv2) - the old macro behaviour can be
restored by defining _CURSES_USE_MACROS.
Changed function prototypes to use ANSI style.
All externally visible functions now have ANSI style declarations.
