        * exceptions.cc (stack_info::walk): Add workaround for NT 5.2
        64 bit OSes.
        * wincap.h (wincaps::has_restricted_stack_args): New element.
        * wincap.cc: Implement above element throughout.
        (wincapc::init): Reset has_restricted_stack_args if not running
        under WOW64.
