+# SYNOPSIS
+#
+# AX_WITH_CURSES
+#
+# DESCRIPTION
+#
+# This macro checks whether a SysV or X/Open-compatible Curses library is
+# present, along with the associated header file. The NcursesW
+# (wide-character) library is searched for first, followed by Ncurses,
+# then the system-default plain Curses. The first library found is the
+# one returned.
+#
+# The following options are understood: --with-ncursesw, --with-ncurses,
+# --without-ncursesw, --without-ncurses. The "--with" options force the
+# macro to use that particular library, terminating with an error if not
+# found. The "--without" options simply skip the check for that library.
+# The effect on the search pattern is:
+#
+# (no options) - NcursesW, Ncurses, Curses
+# --with-ncurses --with-ncursesw - NcursesW only [*]
+# --without-ncurses --with-ncursesw - NcursesW only [*]
+# --with-ncursesw - NcursesW only [*]
+# --with-ncurses --without-ncursesw - Ncurses only [*]
+# --with-ncurses - NcursesW, Ncurses [**]
+# --without-ncurses --without-ncursesw - Curses only
+# --without-ncursesw - Ncurses, Curses
+# --without-ncurses - NcursesW, Curses
+#
+# [*] If the library is not found, abort the configure script.
+#
+# [**] If the second library (Ncurses) is not found, abort configure.
+#
+# The following preprocessor symbols may be defined by this macro if the
+# appropriate conditions are met:
+#
+# HAVE_CURSES - if any SysV or X/Open Curses library found
+# HAVE_CURSES_ENHANCED - if library supports X/Open Enhanced functions
+# HAVE_CURSES_COLOR - if library supports color (enhanced functions)
+# HAVE_CURSES_OBSOLETE - if library supports certain obsolete features
+# HAVE_NCURSESW - if NcursesW (wide char) library is to be used
+# HAVE_NCURSES - if the Ncurses library is to be used
+#
+# HAVE_CURSES_H - if <curses.h> is present and should be used
+# HAVE_NCURSESW_H - if <ncursesw.h> should be used
+# HAVE_NCURSES_H - if <ncurses.h> should be used
+# HAVE_NCURSESW_CURSES_H - if <ncursesw/curses.h> should be used
+# HAVE_NCURSES_CURSES_H - if <ncurses/curses.h> should be used
+#
+# (These preprocessor symbols are discussed later in this document.)
+#
+# The following output variable is defined by this macro; it is precious
+# and may be overridden on the ./configure command line:
+#
+# CURSES_LIB - library to add to xxx_LDADD
+#
+# The library listed in CURSES_LIB is NOT added to LIBS by default. You
+# need to add CURSES_LIB to the appropriate xxx_LDADD line in your
+# Makefile.am. For example:
+#
+# prog_LDADD = @CURSES_LIB@
+#
+# If CURSES_LIB is set on the configure command line (such as by running
+# "./configure CURSES_LIB=-lmycurses"), then the only header searched for
+# is <curses.h>. The user may use the CPPFLAGS precious variable to
+# override the standard #include search path. If the user needs to
+# specify an alternative path for a library (such as for a non-standard
+# NcurseW), the user should use the LDFLAGS variable.
+#
+# The following shell variables may be defined by this macro:
+#
+# ax_cv_curses - set to "yes" if any Curses library found
+# ax_cv_curses_enhanced - set to "yes" if Enhanced functions present
+# ax_cv_curses_color - set to "yes" if color functions present
+# ax_cv_curses_obsolete - set to "yes" if obsolete features present
+#
+# ax_cv_ncursesw - set to "yes" if NcursesW library found
+# ax_cv_ncurses - set to "yes" if Ncurses library found
+# ax_cv_plaincurses - set to "yes" if plain Curses library found
+# ax_cv_curses_which - set to "ncursesw", "ncurses", "plaincurses" or "no"
+#
+# These variables can be used in your configure.ac to determine the level
+# of support you need from the Curses library. For example, if you must
+# have either Ncurses or NcursesW, you could include:
+#
+# AX_WITH_CURSES
+# if test "x$ax_cv_ncursesw" != xyes && test "x$ax_cv_ncurses" != xyes; then
+# AX_MSG_ERROR([requires either NcursesW or Ncurses library])
+# fi
+#
+# If any Curses library will do (but one must be present and must support
+# color), you could use:
+#
+# AX_WITH_CURSES
+# if test "x$ax_cv_curses" != xyes || test "x$ax_cv_curses_color" != xyes; then
+# AC_MSG_ERROR([requires an X/Open-compatible Curses library with color])
+# fi
+#
+# Certain preprocessor symbols and shell variables defined by this macro
+# can be used to determine various features of the Curses library. In
+# particular, HAVE_CURSES and ax_cv_curses are defined if the Curses
+# library found conforms to the traditional SysV and/or X/Open Base Curses
+# definition. Any working Curses library conforms to this level.
+#
+# HAVE_CURSES_ENHANCED and ax_cv_curses_enhanced are defined if the
+# library supports the X/Open Enhanced Curses definition. In particular,
+# the wide-character types attr_t, cchar_t and wint_t, the functions
+# wattr_set() and wget_wch() and the macros WA_NORMAL and _XOPEN_CURSES
+# are checked. The Ncurses library does NOT conform to this definition,
+# although NcursesW does.
+#
+# HAVE_CURSES_COLOR and ax_cv_curses_color are defined if the library
+# supports color functions and macros such as COLOR_PAIR, A_COLOR,
+# COLOR_WHITE, COLOR_RED and init_pair(). These are NOT part of the
+# X/Open Base Curses definition, but are part of the Enhanced set of
+# functions. The Ncurses library DOES support these functions, as does
+# NcursesW.
+#
+# HAVE_CURSES_OBSOLETE and ax_cv_curses_obsolete are defined if the
+# library supports certain features present in SysV and BSD Curses but not
+# defined in the X/Open definition. In particular, the functions
+# getattrs(), getcurx() and getmaxx() are checked.
+#
+# To use the HAVE_xxx_H preprocessor symbols, insert the following into
+# your system.h (or equivalent) header file:
+#
+# #if defined(HAVE_NCURSESW_CURSES_H)
+# # include <ncursesw/curses.h>
+# #elif defined(HAVE_NCURSESW_H)
+# # include <ncursesw.h>
+# #elif defined(HAVE_NCURSES_CURSES_H)
+# # include <ncurses/curses.h>
+# #elif defined(HAVE_NCURSES_H)
+# # include <ncurses.h>
+# #elif defined(HAVE_CURSES_H)
+# # include <curses.h>
+# #else
+# # error "SysV or X/Open-compatible Curses header file required"
+# #endif
+#
+# For previous users of this macro: you should not need to change anything
+# in your configure.ac or Makefile.am, as the previous (serial 10)
+# semantics are still valid. However, you should update your system.h (or
+# equivalent) header file to the fragment shown above. You are encouraged
+# also to make use of the extended functionality provided by this version
+# of AX_WITH_CURSES, as well as in the additional macros
+# AX_WITH_CURSES_PANEL, AX_WITH_CURSES_MENU and AX_WITH_CURSES_FORM.

+# HAVE_PANEL - if the Panel library is present

+# HAVE_NCURSES_PANEL_H - if <ncurses/panel.h> should be used
+# HAVE_NCURSESW_PANEL_H - if <ncursesw/panel.h> should be used

+# The following output variables may be defined by these macros; these are
+# precious and may be overridden on the ./configure command line:
+#
+# PANEL_LIB - library to add to xxx_LDADD before CURSES_LIB
+# MENU_LIB - library to add to xxx_LDADD before CURSES_LIB
+# FORM_LIB - library to add to xxx_LDADD before CURSES_LIB
+#
+# These libraries are NOT added to LIBS by default. You need to add them
+# to the appropriate xxx_LDADD line in your Makefile.am in front of the
+# equivalent CURSES_LIB incantation. For example:
+#
+# prog_LDADD = @PANEL_LIB@ @CURSES_LIB@
+#
+# If one of the xxx_LIB variables is set on the configure command line
+# (such as by running "./configure PANEL_LIB=-lmypanel"), then the header
+# file searched must NOT contain a subpath. In this case, in other words,
+# only <panel.h> would be searched for. The user may use the CPPFLAGS
+# precious variable to override the standard #include search path.
+#
+# The following shell variables may be defined by these macros:
+#
+# ax_cv_panel - set to "yes" if Panels library is present
+# ax_cv_menu - set to "yes" if Menu library is present
+# ax_cv_form - set to "yes" if Form library is present
+#
+# These variables can be used in your configure.ac to determine whether a
+# library you require is actually present. For example:
+#
+# AX_WITH_CURSES
+# if test "x$ax_cv_curses" != xyes; then
+# AC_MSG_ERROR([requires a SysV or X/Open-compatible Curses library])
+# fi
+# AX_WITH_CURSES_PANEL
+# if test "x$ax_cv_panel" != xyes; then
+# AC_MSG_ERROR([requires the Curses Panel library])
+# fi
+#
+# To use the HAVE_xxx_H preprocessor symbols, insert the following into
+# your system.h (or equivalent) header file:
+#
+# For AX_WITH_CURSES_PANEL:
+#
+# #if defined(HAVE_NCURSESW_PANEL_H)
+# # include <ncursesw/panel.h>
+# #elif defined(HAVE_NCURSES_PANEL_H)
+# # include <ncurses/panel.h>
+# #elif defined(HAVE_PANEL_H)
+# # include <panel.h>
+# #else
+# # error "SysV-compatible Curses Panel header file required"
+# #endif
+#
+# For AX_WITH_CURSES_MENU:
+#
+# #if defined(HAVE_NCURSESW_MENU_H)
+# # include <ncursesw/menu.h>
+# #elif defined(HAVE_NCURSES_MENU_H)
