when compiling code that uses ODB 2.4.0 with Visual Studio 2015 one gets many warnings like:

C4275    non - DLL-interface classkey class "std::exception" used as base for DLL-interface classkey struct "odb::exception"    \odb\exception.hxx    19

Furthermore when linking everything together I get the warning

LNK4006    __NULL_IMPORT_DESCRIPTOR already defined in "odb-d.lib(odb-d.dll); second definition ignored.    odb-oracle-d.lib(odb-oracle-d.dll)    1

So far we don't experience any problems based on these warnings, however.
