The above program worked for me just fine.  I changed it a bit (see 
below), but I don't think the difference is significant.
  
Can you run go32-v2 without arguments and post everything it prints?

No, you can't.  But on my machine this works even though the swap file is 
open, so I guess there's some other factor here.

Here's the program that works for me:

#include <stdlib.h>

int main (void)
{
  return system ("chkdsk");
}
