Windows: error C2382: 'beman::optional26::swap': redefinition; different exception specifications

Reproduce la compilación de Windows e inspecciona include/beman/optional26/optional.hpp en las líneas 172 y 1036, donde se informan las declaraciones conflictivas de swap. Después, revisa las pruebas fallidas mencionadas, incluidas optional_ref.t.cpp, optional_range_support.t.cpp y test_types.hpp; se considera terminado cuando los proyectos y las pruebas afectados compilen correctamente en Windows.
