I had planned to respond to your ITS report.

I thought it was normal to support PF_LOCAL in getaddrinfo. It works on
Linux and I think I've seen it some other places. I'll try to check the
specs and maybe also check with some developers why the don't support
it. If the specs say it may not be implemented or developers have a
good reason for not implementing it, I'll add a workaround. Of course
we might have to add a workaround anyway, but I would like to do some
research first.

For now the easiest for you is to comment out #define HAVE_GETADDRINFO 1
in include/portable.h. But if you like some adventure you could see
what happens if you turn on PF_LOCAL in getaddrinfo.c.
