On NetBSD/sparc64 2.1RC2, gcc 3.3.3:
1 2

But that's because the values are passed in registers.  One needs to
use a lot of variables to exceed the available registers.  The
following program produces 2 1076945920 (but still produces 1 2 on
i386):

int pr(a,b,c,d,e,f,g,h,i,j,x,y)
int a,b,c,d,e;
long int x;
int y;
{
 printf("%ld %d\n",x,y);
}
n
int main(ac,av)
int ac;
char **av;
{
 pr(65,66,67,68.69,70,71,72,73,74,1,2);
 return(0);
}
