Printf type modifier wrong or incorrectly documented.

[Ferreira Maurizio]

Seems that the type modifier L is handled incorrectly.
The following program shows garbage instead of the correct result

#include <stdio.h>
#include <stdint.h>

int main (void)
{
  int64_t  i,n;  // idem with long long int

  n = 1;
  for (i = 1; i <= 40; i++)
  {
    printf ("n= %Ld ----- div 1000= %Ld\n",  n, n/1000);
    n = n * 3;
  }
  return 0;
}

Replacing the printf line whith the following, gives the correct answer.

    printf ("n= %I64d ----- div 1000= %I64d\n",  n, n/1000);

I'm trying with mingw32 3.4.2
Is it a bug of libc or of the documentation ?
