Ah, someone followed the guide :-)

It might be a good idea to add a compile time check, it the MSVC_VARIANT 
setting matches the _MSC_VER define. This way, such problems are at 
least harder to make :-)

It's working like a charm, with and without DNS / ADNS enabled.

Without looking too deeply into it, I don't even know why this should go 
wrong. ADNS shouldn't provide any C runtime things that could cause 
trouble because of the different msvcr*.dll versions used. Sorry, no 
idea to help you ...
