Just in case you are maintaining Delphi code for several older versions of Delphi: Be aware that the declarations of NativeInt and NativeUInt are wrong in some of them.

Delphi version SizeOf(Native(U)Int) Win32 SizeOf(Native(U)Int) Win64
1 to 6 not available not available
7 to 2007
8 ← this is wrong
not available
2009 to XE 4 not available
XE2 to XE8 4 8
10.x 4 8

I just stumbled over this in GExperts, which had a wrong IFDEF for overwriting that declaration.
