2011-04-19 Jonathan Wakely <jwakely.gcc@gmail.com> PR libstdc++/48521 * include/std/type_traits (result_of): Handle pointer to member. * include/std/functional (__invoke): Likewise. (_Function_to_function_pointer): Remove. (_Reference_wrapper_base): Provide nested types independent of unary_function and binary_function. (reference_wrapper::operator()): DR 2017. (ref(const A&&), cref(const A&&): Define as deleted. * include/std/future (async): Simplify SFINAE and use result_of to support pointer to member. * testsuite/20_util/reference_wrapper/invoke.cc: Test pointer to member. * testsuite/20_util/reference_wrapper/24803.cc: Likewise. * testsuite/20_util/reference_wrapper/typedefs.cc: Test for types instead of derivation from unary_function and binary_function. * testsuite/20_util/declval/requirements/1_neg.cc: Adjust. * testsuite/20_util/reference_wrapper/invoke-2.cc: New. * testsuite/20_util/reference_wrapper/ref_neg.c: New. * testsuite/20_util/reference_wrapper/typedefs-3.c: New.
