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 INTLSYMBOL must be one of 'external', 'use-libtool'.
+dnl INTLSYMBOL should be 'external' for packages other than GNU gettext, and
+dnl 'use-libtool' for the packages 'gettext-runtime' and 'gettext-tools'.
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 $(top_builddir)/intl/libintl.a will be created.
+dnl AM-DISABLE-SHARED).
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
dnl implementations (in libc or libintl) without the ngettext() function
dnl will be ignored. If NEEDSYMBOL is specified and is
dnl 'need-formatstring-macros', then GNU gettext implementations that don't
dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
dnl INTLDIR is used to find the intl libraries. If empty,
-dnl the value `$(top_builddir)/intl/' is used.
+dnl the value '$(top_builddir)/intl/' is used.

dnl The result of the configuration is one of three cases:
