Yes, unfortunately we have machine with that old thing. Too bad...
Always makes me happy when my code does not work on an older machine ;-)

Thanks. I will do so once back at work.

However, as a first hint:
I was able to compile my stuff after disabling (#if 0) the
following -apparently not needed by me- parts in that header.
Perhaps its an issue with BOOST_PROTO_DEFINE_FUNCTION_TEMPLATE.

 /// as (a.k.a., lexical_cast)
    ///
    BOOST_PROTO_DEFINE_FUNCTION_TEMPLATE(
        1
      , as
      , boost::proto::default_domain
      , (boost::proto::tag::function)
      , ((op::as)(typename))
    )

    /// static_cast_
    ///
    BOOST_PROTO_DEFINE_FUNCTION_TEMPLATE(
        1
      , static_cast_
      , boost::proto::default_domain
      , (boost::proto::tag::function)
      , ((op::static_cast_)(typename))
    )

    /// dynamic_cast_
    ///
    BOOST_PROTO_DEFINE_FUNCTION_TEMPLATE(
        1
      , dynamic_cast_
      , boost::proto::default_domain
      , (boost::proto::tag::function)
      , ((op::dynamic_cast_)(typename))
    )

    /// const_cast_
    ///
    BOOST_PROTO_DEFINE_FUNCTION_TEMPLATE(
        1
      , const_cast_
      , boost::proto::default_domain
      , (boost::proto::tag::function)
      , ((op::const_cast_)(typename))
    )

Perhaps there was a compile problem with these, too:
    /// Usage: construct\<Type\>(arg1, arg2)
    ///
    BOOST_PROTO_DEFINE_VARARG_FUNCTION_TEMPLATE(
        construct
      , boost::proto::default_domain
      , (boost::proto::tag::function)
      , ((op::construct)(typename))
    )

    /// Usage: throw_\<Exception\>(arg1, arg2)
    ///
    BOOST_PROTO_DEFINE_VARARG_FUNCTION_TEMPLATE(
        throw_
      , boost::proto::default_domain
      , (boost::proto::tag::function)
      , ((op::throw_)(typename))
    )

(Can't check right now as someone has shut that machine down. I will on
Monday, though!)

For some reason, my "optional" constructs did not compile either.
(I temp. replaced these by "| *_s"...)
As I said, I will investigate the matter more next Monday.

Best regards, and have a nice weekend
