-Older versions of Sun Forte Developer 6 update 2 have a compiler bug
-that cause "make check" to fail with a "Encounter BINCL entry"
-diagnostic. To fix the bug, update to the latest set of Solaris and
-Forte patches recommended by Sun.
+** Internationalization
+Bison supports two catalogues: one for Bison itself (i.e., for the
+maintainer-side parser generation), and one for the generated parsers
+(i.e., for the user-side parser execution). The requirements between
+both differ: bison needs ngettext, the generated parsers do not. To
+simplify the build system, neither are installed if ngettext is not
+supported, even if generated parsers could have been localized. See
+http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html for
+more details.
