On several 64-bit platforms we encourage using 32-bit compilation and binaries by default because: 1) they're a lot faster than their 64-bit counterparts 2) they're a lot smaller than their 64-bit counterparts 3) 64-bits buys them absolutely nothing Therefore the 32-bit compatability layer must be as fully supportive as humanly possible. Most 64-bit platforms still have %99 32-bit distributions. This has been discussed to death a million times, please accept the situation and work towards getting the 32-bit compat stuff working for these wireless ioctls. We wouldn't be working on this if "just compile as 64-bit" we an acceptable solution now would we :)
