> This is Microsoft's idea of a joke, I guess.  They are trying to become security conscious, so they decided to mark all sort of functions as "deprecated."  You can ignore these errors.  I will be checking in a fix that disables them.
> Also, I suspect you will have to disable the COM wrappers, because they will probably not build in 64-bit mode.  I don't think anyone is even maintaining them now, and I'm not sure if COM can work with 64-bit applications.

> If you want to track these fixes, feel free to create Jira enhancement request, and I'll make sure to update it when the fixes are in the SVN repository.
