Hello,
On 32-bit Windows, dwExtraInfo was a DWORD. But since the transition to x86_64, it has now been changed to a ULONG_PTR. The MSDN specifies that it should be a ULONG_PTR.
In druntime/winuser.d, dwExtraInfo in most structs is a ULONG_PTR, but not always. For example, in MOUSEHOOKSTRUCT it is still a DWORD, which can cause inconsistencies (NULL cannot implicitly be used as a value, for example).
To fix this issue:
KBDLLHOOKSTRUCT
MOUSEHOOKSTRUCT
In both of these structs, dwExtraInfo needs to be a ULONG_PTR instead of a DWORD.
I could be wrong with my assertion, but I'm only comparing the D Windows API to the MSDN to find these inconsistencies.
Regards,
Kelet

I'll fix this and the others in issue 15959.
