What do you mean by portable?  random_device is inherently non-portable 
because it's.... random ;)

In many ways this is something that the std:: version does best as the 
system implementer knows best how to implement on their OS.  Or you 
could just link to Boost.Random of course which would work nearly 
everywhere too I'm sure.

Best, John.
