Windows only headers installed on linux

[hobbes1069]

I'm try to do an abi compairison between versio 0.14 and 0.15 but compiling of the headers fails due to windows only headers being installed. It looks like anything with "WNT" in the name is windows only as well as "NCollection_Haft.h" at a minimum.

I can try to find all the offending headers and "rm -f" them during the packaging process but it would be nice if they weren't installed in the first place.
