NetBSD/lib/libcurses/border.c
blymn aaf74682b9 Added functions to replace what were previously macros in curses.h
(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.
