Debug and release - compiled without any problems.

Release(XP) - many errors

[UnrealKaraulov]

#ifdef XP_BUILD
typedef struct IUnknown IUnknown;
#endif

in top of Confih.h file fix this error, but got more:

3rd_party\rewolf-wow64ext\src\cmemptr.h(37) error C3861: 'free': identifier not found

and

3rd_party\rewolf-wow64ext\src\wow64ext.cpp(397): error C2143: syntax error: missing ')' before '__stdcall' 

[UnrealKaraulov]

#include <stdlib.h>

in cmemptr.h for 'free' not found

[UnrealKaraulov]

#include <winternl.h>
#ifndef BASETYPES
#define BASETYPES
typedef unsigned long ULONG;
typedef ULONG* PULONG;
typedef unsigned short USHORT;
typedef USHORT* PUSHORT;
typedef unsigned char UCHAR;
typedef UCHAR* PUCHAR;
typedef _Null_terminated_ char* PSZ;
#endif 

After <windows.h> in wow64ext.cpp for fix missing ) before stdcall

[UnrealKaraulov]

@DarthTon this can fix Release(XP) build with 2022 visual studio.
