FIELD_OFFSET is defined in include/winnt.h.

Now I could include winnt.h into include/wine/list.h but that doesn't
seem right. I could also copy it,but having two difinitions of the
same macro is also not right. I'm also sure that moving the definition
from include/winnt.h to include/wine/list.h will break existing code.

Any suggestions for dealing with this?
