Ah yeah, nice. so the prefixes can be dropped. Another reason I don't want to
change the enum to an enun class is, from the comments it seems a lot of the
use of unsigned is to avoid the differences in how Win32 vs *nix handle enums
(signed vs unsigned I think). I'll post a follow up with the scoping.
