stack doesn't grow with C++

[Joerg Bornemann]

Hello!

I'm using GNU Bison 1.3.5 (GNUWin32 distribution) and MS C++ 7.1.
I encountered the problem that my parser produces stack overflow errors 
if the stack size becomes > YYINITDEPTH (== 200).

Looking at the generated file produced:

#if (! defined (yyoverflow) \
     && (! defined (__cplusplus) \
         || ((YYLTYPE_IS_TRIVIAL && YYSTYPE_IS_TRIVIAL)))
///...
/// definitions of YYSTACK_RELOCATE and other stuff
//...
#endif

Why has the stack a fixed size when using C++ unless YYLTYPE_IS_TRIVIAL 
is defined (YYSTYPE_IS_TRIVIAL is defined in my generated file)?


Thanks in advance!
