# Macro to add for using GNU gettext.
# Ulrich Drepper <drepper@cygnus.com>, 1995.

# Modified to never use included libintl.

# This file can be copied and used freely without restrictions. It can
# be used in projects which are not available under the GNU Public License
# but which still want to provide support for the GNU gettext functionality.
# Please note that the actual code is *not* freely available.

# If you make changes to this file, you MUST update the copy in
# acinclude.m4. [ aclocal dies on duplicate macros, so if
# we run 'aclocal -I macros/' then we'll run into problems
# once we've installed glib-gettext.m4 :-( ]
