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.
