# Macro to add for using GNU gettext.

# Ulrich Drepper <drepper@cygnus.com>, 1995, 1996

#

# Modified to never use included libintl. 

# Owen Taylor <otaylor@redhat.com>, 12/15/1998

#

# Major rework to remove unused code

# Owen Taylor <otaylor@redhat.com>, 12/11/2002

#

# Added better handling of ALL_LINGUAS from GNU gettext version 

# written by Bruno Haible, Owen Taylor <otaylor.redhat.com> 5/30/3002

#

# Modified to require ngettext

# Matthias Clasen <mclasen@redhat.com> 08/06/2004

#

# We need this here as well, since someone might use autoconf-2.5x

# to configure GLib then an older version to configure a package

# using AM_GLIB_GNU_GETTEXT
