That function is missing a BOTAN_DLL annotation so it does not get
exported by the DLL. Are you calling this function directly in your
code? If so hacking a BOTAN_DLL into the declaration should fix it. If
not it points to possibly some other issue (probably with cvc) so I'd
want to investigate further in that case.
