[odb-users] Compiler Warning (level 2) C4275

[Dev Programmer]

Hello

When I try to build libodb in my Visual Studio 2015 I get
compiler warning (level 2) C4275 for class "odb::exception".
See
https://docs.microsoft.com/ru-ru/cpp/error-messages/compiler-warnings/compiler-warning-level-2-c4275?view=vs-2017

// -- CODE --
namespace odb
{
  struct LIBODB_EXPORT exception: std::exception, details::shared_base
  {
    virtual const char*
    what () const throw () = 0;

    virtual exception*
    clone () const = 0;
  };

  namespace common
  {
    using odb::exception;
  }
}
// -- END CODE --

Parent class std::exception was not exported.
