--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Ed, could you take a look at this please?

These testcases are invalid as std::generate_canonical must be instantiated for
floating-point types, not unsigned int:

ext/random/hypergeometric_distribution/operators/serialize.cc
ext/random/hypergeometric_distribution/operators/values.cc

Do we need a new __generate_canonical for int types?

Also, we should fix all the bogus references to clauses in the standard for the
non-standard distributions:
