[PATCH v6 0/1] MR3294: wow64win: Always use NtUserSetWindowLongPtr() for GWLP_WNDPROC.

[Sven Baars (＠sbaars)]

This fixes SetWindowLongPtr on WoW64. On 32-bit, we have

```
#define                       SetWindowLongPtrA SetWindowLongA
#define                       SetWindowLongPtrW SetWindowLongW
```

meaning that on WoW64, all pointers passed would be padded with `0xffffffff` (because they are treated as LONG), and this is the cause of many of the failing WoW64 tests. This fixes that behavior. I'm not sure if this is the right place to fix it though.

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:
