I'm seeing a few errors after that change, first of all, is_pod appears not to be improved by the change: is_pod_test.cpp:156: <note>The expression: "::boost::is_pod<empty_POD_UDT>::value" did not have the value we wish it to have (found 0, expected 1)</note> is_pod_test.cpp:157: <note>The expression: "::boost::is_pod<POD_UDT>::value" did not have the value we wish it to have (found 0, expected 1)</note> is_pod_test.cpp:158: <note>The expression: "::boost::is_pod<POD_union_UDT>::value" did not have the value we wish it to have (found 0, expected 1)</note> is_pod_test.cpp:159: <note>The expression: "::boost::is_pod<empty_POD_union_UDT> ::value" did not have the value we wish it to have (found 0, expected 1)</note> But there are also compiler errors from some of the tests: $ dmc -I../../../ has_trivial_copy_test.cpp ../../../boost/type_traits/has_trivial_copy.hpp(37) : Error: voids have no value ; ctors, dtors and invariants have no return value --- errorlevel 1 John Maddock@fuji /cygdrive/c/data/boost/develop/boost/libs/type_traits/test $ dmc -I../../../ has_trivial_destructor_test.cpp ../../../boost/type_traits/has_trivial_destructor.hpp(31) : Error: voids have no value; ctors, dtors and invariants have no return value --- errorlevel 1 Which arise from testing volatile qualified types.
