++
++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.

++dnl
++dnl The header files may be installed as either curses.h, or ncurses.h (would
++dnl be obsolete, except that some packagers prefer this name to distinguish it
++dnl from a "native" curses implementation). If not installed for overwrite,
++dnl the curses.h file would be in an ncurses subdirectory (e.g.,
++dnl /usr/include/ncurses), but someone may have installed overwriting the
++dnl vendor's curses. Only very old versions (pre-1.9.2d, the first autoconf'd
++dnl version) of ncurses don't define either __NCURSES_H or NCURSES_VERSION in
++dnl the header.
++dnl
++dnl If the installer has set $CFLAGS or $CPPFLAGS so that the ncurses header
++dnl is already in the include-path, don't even bother with this, since we cannot
++dnl easily determine which file it is. In this case, it has to be <curses.h>.
++dnl
++dnl The optional parameter gives the root name of the library, in case it is
++dnl not installed as the default curses library. That is how the
++dnl wide-character version of ncurses is installed.
