I've applied a patch to HEAD that calls InterlockedCompareExchange directly if
_WIN64 is defined, and uses the existing ice_wrapper code otherwise. This
patch has been outstanding for a while.

Could someone who's running a 64-bit version of Windows please test this. If
it works fine, we could apply it to the release branch.
