The problem is that stdin and stdout are not constant pointers, but
are macros which get replaced by function calls (it may be compiler
dependant, I'm not sure of the standard).  I think the following
would work:

#include <stdio.h>
FILE *yyin, *yyout;
main()
{
   ...
   yyin = stdin;
   yyout = stdout;
   ...
}

Check your stdio.h to see how stdin and stdout are defined.
