64 bit applications and typelib files

Are there any source (.idl file) changes that should be made to create a typelib project targeting the x64 platform?

It appears to me (so far) that there is no real difference in the type library that is created for the Win32 target and the x64 target.

Remember that the idl and COM always used a data marshalling schema that is platform independant. So it was the intent from the start of COM to have a standard discription and type system.
So don't wonder about it, use it :-)
