Hmmm.... may I ask why? Unifying hooking mechanism seems like a good idea to me and it's not like it's gonna add any runtime overhead although it does complicate init/exit but well that's something you have to pay if you wanna do things dynamically and sans the ifdef stuff it's like a couple hundred lines of isolated code.
Thanks.
