Re: [boost] Re: [program_options, type_traits] is_reference and VC 7.0

Not portable, as the library implementer is free to add additional template parameters, so long as they have default values.

100% agreement in principle.

Of course if you know exactly which implementation you are dealing with, you can arrange the correct fwd-declaration <g>

I suspect we're only really dealing with VC6 and 7 here, so I guess it is possible in this case. John.
