OK, with the same caveats, here are the double precision results:

[6] % f77 -O -o stream_d stream_d.f second.o
stream_d.f:
   MAIN stream:
   realsize:
   dummy:
[7] % stream_d
--------------------------------------
 Double precision appears to have 16 digits of accuracy
 Assuming 8 bytes per DOUBLEPRECISION word
--------------------------------------
 Timing calibration ; time = 35.99999919533729 hundredths of a second
 Increase the size of the arrays if this is <30
  and your clock precision is =<1/100 second
