* URGENT: Prologue * Several %unions
The %union is declared after the user C declarations. It can be I think this is a pleasant (but useless currently) feature, but in the

Actually, the real problem seems that the %union ought to be output %union.
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.
Note that we have the same problem with GCC.
I suggest splitting the prologue into pre-prologue and post-prologue.
The reason is that:
1. we keep language independance as it is the skeleton that joins the
two prologues (there is no need for the engine to encode union yystype
and to output it inside the prologue, which breaks the language
independance of the generator)
2. that makes it possible to have several %union in input. I think
this is a pleasant (but useless currently) feature, but in the future,
I want a means to %include other bits of grammars, and _then_ it will
be important for the various bits to define their needs in %union.
When implementing multiple-%union support, bare the following in mind: When implementing multiple-%union support, bare the following in mind:
