DUMMYSTRUCT is defined as nothing if the compiler supports
nameless structs. GNU C++ was mistakenly believed by me to support
nameless structs. I didn't check however, I have check now
and it seem like no version of GNU C++ does. :-(
Not that it really needs to support it since you could get the same
effect with "dummy" structs/classes and inheritence, but then I
really can't see any particular reason not to support it since
makes at least as much sense (if not more) in C++ to have unnamed
structs as in C...
Anyway, there is a patch in wine-patches that fixes the problem and
since it as I said is always possible to "fake it" in C++ there
is no great need to ask the GNU C++ developers the fix the problem
