10941	boost/multiprecision/cpp_int/misc.hpp uses boost::math::gcd (and lcm), but does not include common_factor_rt.hpp	Peter Dimov	John Maddock	"At line 508:

{{{
   *result.limbs() = boost::math::gcd(*a.limbs(), *b.limbs());
}}}

This is in a template, so MSVC has no problems with it, only g++ and clang++ complain.

The reason this was not a problem before was that boost/multiprecision/rational_adaptor.hpp uses Rational, which used to include math/common_factor_rt.hpp, but no longer does.

Either math:: should be made integer::, the include added, or both.
