When testing, it would help if the results were properly
represented as your initial subject line was "Random seed
initialization".  It seems clear to at least me your testing
did not include actually inspecting what these two lines do:

   CALL SYSTEM_CLOCK(COUNT=clock)
   seed = clock + 37 * (/ (i-1), 1=1, n) /)

because your subject would have been "SYSTEM_CLOCK is broken
on cygwin".

If you want to see an actual issue with "Random seed initialization"
go read PR 52879.
