Different random shuffles generated when compiled with gdc than with dmd

[Wanderer via Digitalmars-d-learn]

I must note if the sequence is predictable, it's not random 
anymore, it's pseudo-random at most.

Also, if anyone interested, PHP had such way to generate 
predictable sequences in the past, but after it was horribly 
misused by various people for crypto keys/password generation 
purposes, they have forbidden it completely, so only 
non-predictable sequences in PHP from now on. Maybe, just maybe, 
it makes sense not to stand on the same rack twice.
