Hello everyone,
i am using djgpp 2.00 for long under Win 95/98, and it worked
great for me. Now i aquired a new machine running XP home and tried to
move my applications. The first step was update to 2.03, which solved
most problems, but one remains: delay does not work any more. The
function returns immediately regardless of the argument i
provide. After a look into the source I gave up: delay.c runs:

  /* Copyright (C) 1995 DJ Delorie, see COPYING.DJ for details */
  #include <dos.h>
  #include <dpmi.h>

  void delay(unsigned msec)
  {
    __dpmi_regs r;
    while (msec)
    {
      unsigned usec;
      unsigned msec_this = msec;
      if (msec_this > 4000)
        msec_this = 4000;
      usec = msec_this * 1000;
      r.h.ah = 0x86;
      r.x.cx = usec>>16;
      r.x.dx = usec & 0xffff;
      __dpmi_int(0x15, &r);
      msec -= msec_this;
    }
  }

and i have no idea what goes wrong. Any ideas? Or did i miss something
in the docs?

TIA
        Dirk
