The problem is at build time.. there is no msghdr on Windows. So either I emulate it via a squid-specific struct (which is what I'm attempting), or the data model needs changes so that it owns a msghdr instead of inheriting from one, so that on Linux it can be a msghdr, on windows it can be something else.. Otherwise TypedMsgHdr will end up being a Swiss cheese of #ifndefs _SQUID_WINDOWS_ .. -- /kinkie
