Sorry, I don't understand. Since all template member functions are inline in
MSVC, how can they interact with anything at link time?

Thanks,
Dave

Hi,

as I posted earlier in the messages 2635 mensioned below: You cannot export
classes with member templates from a DLL. In my case I have a lot of classes
using smart pointers that are exported from a DLL. If you enable the member
templates this is no longer possible because MSVC tries to import the new
instance of the member template from that DLL that contains the export of
the instanciated class.

So I have great objections removing BOOST_MSVC6_MEMBER_TEMPLATES !

Greetings,
Jörg
