Maybe I misunderstood what you said, but gcc reports no errors with this program
compiled with "gcc -Wall test.c":

int *Func1(int *Pointer)
  {
  Pointer += 5;
  Pointer[5] = 10;

  return Pointer;
  }

int *Func2(int Pointer[])
  {
  Pointer += 5;
  Pointer[5] = 10;

  return Pointer;
  }


int main(void)
  {
  int                            Variable[100];

  Func1(Variable);
  Func2(Variable);

  return 1;
  }

Note that both functions modify the pointer and place information into the
array.  Did I misunderstand what you were saying?
