Ie different between Windows & *nix. And that is the cause of the failures for the obfu

Yes, I think that's the cause of most of the failures - but not the one that Athanasius experienced with Strawberry Perl. My Strawberry Perl 5.20.0 produces the same as Athanasius got: 
C:\_32\strawberry5.20.0>perl -e "srand 42; print sort {4-rand 9} split
+ //, 'ts aroMrhirsae C tll!!ym';"
l ttyaMeos  arrCsrihm!!l

But when I switch to 5.18.2 it all works as intended: 
C:\_32\strawberry5.18.2>perl -e "srand 42; print sort {4-rand 9} split
+ //, 'ts aroMrhirsae C tll!!ym';"
Merry Christmas to all!!
C:\_32\strawberry5.18.2>

And it also works as expected for me all the way back to 5.8.8 (which is as far back as I go).

From 5.20 on, that problem goes away because of the built-in rand/srand rather inheriting them from the platform C compiler implementation.

Agreed, and it was worth doing for that very reason.
I just think they should have mentioned, in the srand documentation, that srand(42) would produce different results (on Windows) for 5.20.0 as compared to earlier perl versions - but the srand documentation (as it stands) suggests to me that no such change is to be expected.

Cheers,
Rob
