	PR libstdc++/60037 - SIGFPE in std::generate_canonical<unsigned int...>
	* include/bits/random.h (_Adaptor): static_assert for non floating-point
	result type.
	* include/bits/random.tcc (generate_canonical): Ditto.
	* include/ext/random.tcc (hypergeometric_distribution::operator()):
	Use double as a rng result type.
	* testsuite/26_numerics/random/pr60037-neg.cc: New.
	* testsuite/ext/random/hypergeometric_distribution/pr60037.cc: New.
