I trump thee collectively:

void print_arg(int *aryp, size_t n)
{

   char *t="%u,";
   int i=0;

   for (;(i==n-1 ? t="%u" : i<n);) printf(t, *aryp + i++);

   putchar('\n');

}

A little ugly (the compiler complains about the type mismatch in the unary
expression) but otherwise it works without caveats (that I know of ;)

I suspect someone might bum it down further...no more precious time to
expend on this useless pursuit ;)
