# SYNOPSIS
#
# AX_WITH_CURSES
#
# DESCRIPTION
#
# Detect SysV compatible curses, such as ncurses.
#
# Defines HAVE_CURSES_H or HAVE_NCURSES_H if curses is found. CURSES_LIB
# is also set with the required library, but is not appended to LIBS
# automatically. If no working curses library is found CURSES_LIB will be
# left blank. If CURSES_LIB is set in the environment, the supplied value
# will be used.
#
# There are two options: --with-ncurses forces the use of ncurses, and
# --with-ncursesw forces the use of ncursesw (wide character ncurses). The
# corresponding options --without-ncurses and --without-ncursesw force
# those libraries not to be used. By default, ncursesw is preferred to
# ncurses, which is preferred to plain curses.
#
# ax_cv_curses is set to "yes" if any curses is found (including
# ncurses!); ax_cv_ncurses is set to "yes" if any ncurses is found, and
# ax_cv_ncursesw is set to "yes" if ncursesw is found.
