Hello,

this is by design = exactly what Windows does.

See MSDN:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms633585%28v=vs.85%29.aspx

--- quote ---
To write code that is compatible with both 32-bit and 64-bit versions of
Windows, use GetWindowLongPtr. When compiling for 32-bit Windows,
GetWindowLongPtr is defined as a call to the GetWindowLong function.
--- quote ---

"defined as a call" means it is mapped to GetWindowLongA/W at compile time
(header file -> preprocessor).
See comment from "paulbassett13" (8/15/2010).

Wine source:
http://source.winehq.org/git/wine.git/blob/4180054c2fcd9b0fca0f3ef32c75af50d527d06d:/include/winuser.h#l3638

--- snip ----
3638 #ifdef _WIN64
3639 WINUSERAPI LONG_PTR    WINAPI GetWindowLongPtrA(HWND,INT);
3640 WINUSERAPI LONG_PTR    WINAPI GetWindowLongPtrW(HWND,INT);
3641 #else
3642 #define                       GetWindowLongPtrA GetWindowLongA
3643 #define                       GetWindowLongPtrW GetWindowLongW
3644 #endif
--- snip ----
