I pushed these, except I chopped out the HAVE_UNIX_SOCKETS part as
requested. Here it is in a separate patch, with a commit message that
explains the rationale (essentially, what you said, it's basically a
runtime matter for a hypothetical AF_UNIX-less system to complain
about). Tom, does this argument persuade you? Also, a couple of
nearby things:
Remove HAVE_UNIX_SOCKETS.
Remove configure probe for struct sockaddr_storage.
Remove configure probe for getaddrinfo, and replacement code.
If I'm reading comments and scraped configure data right, it looks
like those last two things were there only for HP-UX 10 and Windows <
8.1.
I tried to figure out how to get rid of
PGAC_STRUCT_SOCKADDR_STORAGE_MEMBERS, but there we're into genuine
non-standard cross-platform differences. At best maybe you could
maybe skip the test for ss_family (POSIX says you have to have that,
but I haven't read RFC 2553 to see why it claims someone should spell
it differently). Didn't seem worth changing.

Subject: [PATCH 1/3] Remove HAVE_UNIX_SOCKETS.
Since HAVE_UNIX_SOCKETS is now defined unconditionally, remove the macro
and drop a small amount of dead code.
The last known systems not to have them (as far as I know at least) were
QNX, which we de-supported years ago, and Windows, which now has them.
If a hypothetical new OS shows up with the POSIX sockets API but without
working AF_UNIX, it'll presumably still be able to compile the code, and
fail at runtime with unsupported address family. We might want to
consider adding a HINT that you should turn it off if your OS doesn't
support it at that point, but it doesn't seem worth making the relevant
code compile-time conditional.

From d11c344a0cc59d6e657073d243358be16347907c Mon Sep 17 00:00:00 2001

Subject: [PATCH 3/3] Remove configure probe for getaddrinfo, and replacement
code.
SUSv3 and modern Windows have getaddrinfo() and related interfaces.
Drop the replacement implementation, and adjust some headers slightly to
make sure that the OS APIs are visible on both OSes using POSIX header
names.
