dnl CF_TYPE_OUTCHAR version: 13 updated: 2002/10/09 20:00:37
dnl ---------------
dnl Check for return and param type of 3rd -- OutChar() -- param of tputs().
dnl
dnl For this check, and for CF_CURSES_TERMCAP, the $CHECK_DECL_HDRS variable
dnl must point to a header file containing this (or equivalent):
dnl
dnl	#ifdef NEED_CURSES_H
dnl	# ifdef HAVE_NCURSES_NCURSES_H
dnl	#  include <ncurses/ncurses.h>
dnl	# else
dnl	#  ifdef HAVE_NCURSES_H
dnl	#   include <ncurses.h>
dnl	#  else
dnl	#   include <curses.h>
dnl	#  endif
dnl	# endif
dnl	#endif
dnl
dnl	#ifdef HAVE_NCURSES_TERM_H
dnl	#  include <ncurses/term.h>
dnl	#else
dnl	# ifdef HAVE_TERM_H
dnl	#  include <term.h>
dnl	# endif
dnl	#endif
dnl
dnl	#if NEED_TERMCAP_H
