Hi Anton et al,
The copyright file of metis says the following is the license for
GKlib/random.c:

That's a warranty disclaimer --- it doesn't say anything about how

For comparison,
http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/VERSIONS/C-LANG/mt19937-64.c
has the same code (for the Mersenne-Twister part) and says

Could GKlib/random.c and debian/copyright use that license? Or
alternatively, could metis use another copy of mersenne twister, e.g.
from libgmp if it has one?
Thanks,
Jonathan
