The convention in these modules is to comment anything simply not present that's expected... I'm going to give h_error a look before I decide what to do with it. [edit] Ah, looks like h_error isn't even defined on OSX. I think I'll just leave it commented.

You completely removed NI_MAXHOST and NI_MAXSERV from the file, breaking the Phobos build – the auto-tester is all red!

It's not part of the Posix spec, but present at least on Linux, OS X and FreeBSD (plus Windows, in the WinSock headers).
