> I vaguely recall that we switched to using "unsigned" a while back for bitfields that were enums (I believe that enums are being treated as "signed" by Visual C++). Since these are bools, not enum, what should we be doing here? It would be nice to be consistent.
"bool" is the natural type for these flags, so I suggest we stick with it.
