-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). Otherwise, 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 LIBDIR 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)
