I'd like to ask whether there is any intention to implement the X/Open
extension ' (0x27) printf() format flag. (Numbered argument specifications
work (thanks to Jeff Johnston), and they are an X/Open extension too.)

I encountered this problem using cygwin-1.5.10-3 on an XP.

Illustration:

--------

#define _XOPEN_SOURCE

#include <stdio.h>
#include <assert.h>
#include <locale.h>

int main(void)
{
  assert(setlocale(LC_NUMERIC, ""));

  /* This works. */
  printf("%1$d %1$d\n", 1000);

  /* This does not, even if LC_NUMERIC is C. */
  printf("%'d\n", 1001);

  return 0;
}

Thank you

Laszlo Ersek
