[ace-bugs] use of deprecated std::auto_ptr ?

[Johnny Willemsen]

Hi,

Thanks for using the PRF form. We have seen these warnings, but we just
can't easily switch to unique_ptr because we support a lot of platforms
that don't support C++11 yet. Probably we need to introduce some macros
that expand to auto_ptr or unique_ptr dependent on system settings but
doing that for the full code base is not a small task. Maybe you can do
that or fund such an effort?

Best regards,

Johnny Willemsen
