Unless you are casting pointers to integers or longints, there shouldn't be
much trouble. We have always known that such a cast is liable to run in to
trouble. I think we will be able to write code and libraries which compile
32/64 bit with no trouble.

You can still store a 32 bit integer in a 64 bit object reference or pointer
variable: e.g. in a TList.

I suspect I have zero problems in my own code. Imagine how much strife a
bad C programmer will have, with a typecast on every 3rd line ! At least
they will get compiler warnings, I assume.
