But by simply copying them, you violate the EULA to which you
subscribed when you installed the SDK, (whether you actually read it
or not is immaterial).

IANAL, but I would doubt if this could be construed as "fair use".
While it may be acceptable, in certain circumstances, to reverse
engineer code for the purpose of achieving interoperability, this
really is no different from reading the original sources, with the
intent to pass privileged information to a competitor.

Ok.  This much, we can use then.

So, unless you can find it publicly documented elsewhere, or you
can demonstrate a method for determining it *without* resort to the
SDK, them we must exclude it.

And these can be converted to the appropriate _WIN32_WINNT define
on the basis of publicly accessible information published here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winprog/winprog/using_the_windows_headers.asp
so we can also use that.

Please submit a patch:

Cite the two MSDN references above as your sources, and include
only those defines which are actually documented there.

Thanks,
