Here's what I have been using for fcloseall().  I don't recall v1 having this
function either, so there are #if's to make it work for either v1 or v2.  The
general idea came from a posting here and I filled in the details by looking
at library sources.  Perhaps djgpp maintainers can add this code (v2 variant
only) to a future release.  It's trivial enough that I don't think I need to
give a written copyright release.

#if __GNUC__ > 1
static void close_nonstd(FILE *f)
   {
   if(fileno(f) >4)
      fclose(f);
   }
#endif

int fcloseall(void)
   {
#if __GNUC__ < 2
   int i;

   for(i=5; i<20; i++)
      {
      if(_iob[i]._file > 0)
         fclose(&_iob[i]);
      }
#else
   _fwalk(close_nonstd);
#endif
   return(0);
   }
