+The %union is declared after the user C declarations. It can be
+a problem if YYSTYPE is declared after the user part.  []
+
+Actually, the real problem seems that the %union ought to be output
+where it was defined.  For instance, in gettext/intl/plural.y, we
+have:
+
+       %{
+       ...
+       #include "gettextP.h"
+       ...
+       %}
+
+       %union {
+         unsigned long int num;
+         enum operator op;
+         struct expression *exp;
+       }
+
+       %{
+       ...
+       static int yylex PARAMS ((YYSTYPE *lval, const char **pexp));
+       ...
+       %}
+
+Where the first part defines struct expression, the second uses it to
+define YYSTYPE, and the last uses YYSTYPE.  Only this order is valid.
