Does the approach used in winbase.h in declaration of WIN32_STREAM_ID to
align the Size field help?
#include <pshpack8.h>
typedef struct _WIN32_STREAM_ID {
DWORD dwStreamId;
DWORD dwStreamAttributes;
LARGE_INTEGER DECLSPEC_ALIGN(8) Size;
DWORD dwStreamNameSize;
WCHAR cStreamName[ANYSIZE_ARRAY];
} WIN32_STREAM_ID, *LPWIN32_STREAM_ID;
#include <poppack.h>

This should be a part of auto generated header tests. Have a look at
dlls/*/tests/generated.c files.
