Okay, I can do that.

Any thoughts on which set of flags should override the other?  If we're making
RESOLVE_* flags the new definitive interface, then I feel they should probably
override the AT_* flags where there's a conflict, ie. RESOLVE_NO_SYMLINKS
should override AT_SYMLINK_FOLLOW for example.
