Hello Mr Ramey,

export.hpp includes itself with the comment

// for guid_defined only
(see the diff below)

but guid_defined is in extended_type_info.hpp

so I assume this is a typo

And without the inclusion of extended_type_info.hpp
export.hpp *really* specializes the  undefined template guid_defined, as
the error message posted from Fabien shows.

Regards,

Nikolay Mladenov
