[ofw] Porting OFA stack to WDK

[Fab Tillier]

The size of structures would change, so yes, apps would need to recompile.  You could add #ifdef'd padding to keep the 32-bit structures the same size and preserve binary compatibility.

I think this would require that apps re-compile, but...

I also don't think __ptr64 should be in any user interface functions or
structures.

Do we know if apps would need to recompile?  And, if so, are we okay with that?
Do we want to consider this change for a 2.0 release?
