--------------------------------------------------------------------
-In the bison source:
-%define linef "#line %d %s"
+* Prologue
+The %union is declared after the user C declarations. It can be
+a problem if YYSTYPE is declared after the user part.  []
 
-In output.c:
-if (macro_find ("linef"))
-    obstack_fgrow2 (&table_obstack, macro_find ("linef"),
-    line, filename);
--------------------------------------------------------------------
+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:
 
-Cleanup dirty CPP-out code.    []
-** Output sub-skeleton files.  []
-Useful for %no_parser. []
-*** New skeleton.      []

+
+Where the first part defines struct expression, the second uses it to
+define YYSTYPE, and the last uses YYSTYPE.  Only this order is valid.
