I've never thought it was an issue (re compat) to add some bit(s) in a bitfield if there is a hole, wherever this field is in the struct. It doesn't change the size and there is no way for the user to have used the address of any bit in the first place (it can't break anything IMHO). Bill objected to this, I can't remember why (and he is in better position to explain it), status quo so far... > > 2.4.x currently has a single bit bitfield at the end of the server_rec. Yes, I think there is much less interest in using bitfields if we can't extend them. Regards, Yann.
