+# 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. Finding libraries will first be attempted by using
+# pkg-config, and should the pkg-config files not be available, will
+# fallback to combinations of known flags itself.
+#
+# 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 variables are defined by this macro; they are
+# precious and may be overridden on the ./configure command line:
+#
+# CURSES_LIBS - library to add to xxx_LDADD
+# CURSES_CFLAGS - include paths to add to xxx_CPPFLAGS
+#
+# In previous versions of this macro, the flags CURSES_LIB and
+# CURSES_CPPFLAGS were defined. These have been renamed, in keeping with
+# AX_WITH_CURSES's close bigger brother, PKG_CHECK_MODULES, which should
+# eventually supersede the use of AX_WITH_CURSES. Neither the library
+# listed in CURSES_LIBS, nor the flags in CURSES_CFLAGS are added to LIBS,
+# respectively CPPFLAGS, by default. You need to add both to the
+# appropriate xxx_LDADD/xxx_CPPFLAGS line in your Makefile.am. For
+# example:
+#
+# prog_LDADD = @CURSES_LIBS@
+# prog_CPPFLAGS = @CURSES_CFLAGS@
+#
+# If CURSES_LIBS is set on the configure command line (such as by running
+# "./configure CURSES_LIBS=-lmycurses"), then the only header searched for
+# is <curses.h>. 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
+# AC_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.

+# SYNOPSIS
+#
+# AX_WITH_CURSES_PANEL
+# AX_WITH_CURSES_MENU
+# AX_WITH_CURSES_FORM
+#
+# DESCRIPTION
+#
+# These macros try to find additional libraries that often come with
+# SysV-compatible Curses. In particular, the Panel, Menu and Form
+# libraries are searched, along with their header files. These macros
+# depend on AX_WITH_CURSES.
+#
+# The following preprocessor symbols may be defined by these macros:
+#
+# By AX_WITH_CURSES_PANEL:
+#
+# HAVE_PANEL - if the Panel library is present
+# HAVE_PANEL_H - if <panel.h> is present and should be used
+# HAVE_NCURSES_PANEL_H - if <ncurses/panel.h> should be used
+# HAVE_NCURSESW_PANEL_H - if <ncursesw/panel.h> should be used
+#
+# By AX_WITH_CURSES_MENU:
+#
+# HAVE_MENU - if the Menu library is present
+# HAVE_MENU_H - if <menu.h> is present and should be used
+# HAVE_NCURSES_MENU_H - if <ncurses/menu.h> should be used
+# HAVE_NCURSESW_MENU_H - if <ncursesw/menu.h> should be used
+#
+# By AX_WITH_CURSES_FORM:
+#
+# HAVE_FORM - if the Form library is present
+# HAVE_FORM_H - if <form.h> is present and should be used
+# HAVE_NCURSES_FORM_H - if <ncurses/form.h> should be used
+# HAVE_NCURSESW_FORM_H - if <ncursesw/form.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_LIBS - library to add to xxx_LDADD before CURSES_LIBS
+# MENU_LIBS - library to add to xxx_LDADD before CURSES_LIBS
+# FORM_LIBS - library to add to xxx_LDADD before CURSES_LIBS
+#
+# In previous versions of this macro, the flags PANEL_LIB, MENU_LIB and
+# FORM_LIB were defined. These have been renamed, in keeping with the
+# variable scheme of PKG_CHECK_MODULES, which should eventually supersede
+# the use of AX_WITH_CURSES and AX_WITH_CURSES_* macros. 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_LIBS incantation. For example:
+#
+# prog_LDADD = @PANEL_LIBS@ @CURSES_LIBS@
+#
+# If one of the xxx_LIBS variables is set on the configure command line
+# (such as by running "./configure PANEL_LIBS=-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
+# # include <ncurses/menu.h>
+# #elif defined HAVE_MENU_H
+# # include <menu.h>
+# #else
+# # error "SysV-compatible Curses Menu header file required"
+# #endif
+#
+# For AX_WITH_CURSES_FORM:
+#
+# #if defined HAVE_NCURSESW_FORM_H
+# # include <ncursesw/form.h>
+# #elif defined HAVE_NCURSES_FORM_H
+# # include <ncurses/form.h>
+# #elif defined HAVE_FORM_H
+# # include <form.h>
+# #else
+# # error "SysV-compatible Curses Form header file required"
+# #endif

+dnl Ulrich Drepper <drepper@cygnus.com>, 1995-2000.

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl default (if it is not specified or empty) is 'no-libtool'.
+dnl INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl depending on --{enable,disable}-{shared,static} and on the presence of
+dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl implementations (in libc or libintl) without the ngettext() function
+dnl will be ignored. If NEEDSYMBOL is specified and is
+dnl 'need-formatstring-macros', then GNU gettext implementations that don't
+dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries. If empty,
+dnl the value '$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl and used.
+dnl Catalog format: GNU --> install in $(datadir)
+dnl Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl Catalog format: GNU --> install in $(datadir)
+dnl Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl Catalog format: none
+dnl Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.
