I looked at this. Line 1065 is the left brace starting yyparse(). On
my Fedora Core 5 box with Bison 2.1 installed, the stuff leading up to
it is
#ifdef YYPARSE_PARAM
... some uninteresting stuff, since we don't define YYPARSE_PARAM ...
#else /* ! YYPARSE_PARAM */
#if defined (__STDC__) || defined (__cplusplus)
int
yyparse (void)
#else
int
yyparse ()
#endif
#endif
{
But lookee here, your Windows-built version has
#ifdef YYPARSE_PARAM
...
#else /* ! YYPARSE_PARAM */
#if defined (__STDC__) || defined (__cplusplus)
int
yyparse (void)
#else
int
yyparse ()
;
#endif
#endif
{
So that semicolon is the source of the trouble. That's clearly a bison
bug, and in fact digging in Red Hat's SRPM shows that they are carrying
a patch for it:

## ---------------------------------------- ##
Presumably bison 2.2 includes this fix. But I guess the real question
is why the devil doesn't MSVC define __STDC__ ? Are they that far
removed from spec compliance?
