There have been experiments in the past, but no steady maintainer. Often
there are mails just like yours, partially working, little problems, but no
final verdict. Try to communicate as much as possible back to the Delphi
maintainer.

Note that a define system that works on Delphi versions is fundamentally
flawed, most other open source projects abandonned that; read

That sounds like olevariant stuff. It is supported but only with FPC 2.3.1 (trunk)
afaik. I don't know if P4D is already updated for those (2.3+) changes.
