For example only in FPC dyn. array parameter is passed on stack instead of
by reference (in opposition to Delphi)... with small change in r30870 for
register calling convention (changed for properties). Ofc. is possible to
use constref modifier but... Arghhhh...

The interesting thing about Invoke() will be support on other platforms ;)
We've not yet decided how we'll tackle it...

Dynamic arrays were changed to be passed on stack in 2.7.1 on purpose AFAIK.
