[PATCH 0/1] MR7488: include: Use wchar_t for platform types on PE targets.

[Jacek Caban (＠jacek)]

`WINE_UNICODE_NATIVE` handles non-PE targets where appropriate, but on PE targets, we should always use `wchar_t`. This is particularly important for C++, where `wchar_t` is a distinct built-in type.

[PATCH 1/1] include: Use wchar_t for platform types on PE targets.

[Jacek Caban]

From: Jacek Caban

WINE_UNICODE_NATIVE handles non-PE targets where appropriate, but on PE targets,
we should always use wchar_t. This is particularly important for C++, where
wchar_t is a distinct built-in type.
