Actually, no:

#ifdef MSDOS
  /*
   * There is no way we can refer to them from Perl so close them to
   * save space.  The other alternative would be to provide STDAUX and
   * STDPRN filehandles.
   */
  (void)fclose(stdaux);
  (void)fclose(stdprn);
#endif

It's our stdio cleanup hook that finds the (non-existent) stdprn entry
in the chain of FILEs first and closes it behind the back of the 'real'
file with fd 3.

There is no djdev bugfix for this IIRC; I simply patched perl.c to not
close stdprn on DJGPP and uploaded fixed perl binaries.
