+Another example is this one:
+
+@example
+printf ("%d file%s processed", nfiles,
+ nfiles != 1 ? "s" : "");
+@end example
+
+@noindent
+The problem with this example is that it assumes that plurals are made
+by adding `s'. If you apply gettext to the format string, like this,
+
+@example
+printf (gettext ("%d file%s processed"), nfiles,
+ nfiles != 1 ? "s" : "");
+@end example
+
+@noindent
+the message can use different words, but it will still be forced to use
+`s' for the plural. Here is a better way, with gettext being applied to
+the two strings independently:
+
+@example
+printf ((nfiles != 1 ? gettext ("%d files processed")
+ : gettext ("%d file processed")),
+ nfiles);
+@end example
+
+@noindent
+But this still doesn't work for languages like Polish, which has three
+plural forms: one for nfiles == 1, one for nfiles == 2, 3, 4, 22, 23, 24, ...
+and one for the rest. The GNU @code{ngettext} function solves this problem:
+
+@example
+printf (ngettext ("%d files processed", "%d file processed", nfiles),
+ nfiles);
+@end example
