// requires certain compiler options be set to achieve that strong conformance.
// Particularly /Qoption,c,--arg_dep_lookup (reported by Kirk Klobe & Thomas Witt)
// and /Zc:wchar_t,forScope. See boost-root/tools/build/intel-win32-tools.jam for
// details as they apply to particular versions of the compiler. When the
// compiler does not predefine a macro indicating if an option has been set,
// this config file simply assumes the option has been set.
// Thus BOOST_NO_ARGUMENT_DEPENDENT_LOOKUP will not be defined, even if
// the compiler option is not enabled.
