Nearly ever copy of that file used by various projects are GPL (this is
confirmed by the last link in this email). I have no idea why the one
we're using isn't, it must be an early version.
Here's the original (well actually improved over what we're using, I
think) code at the homepage:

see also license page at
http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/MT2002/elicense.html
BTW, there's a roughly twice-as-fast SIMD implementation at
http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/SFMT/index.html that we
might want to switch to :)
