http://pubs.opengroup.org/onlinepubs/9699919799/ has now been replaced
(see #900882, for which I'm preparing a patch) with POSIX.1-2017, which
is variously labelled as:

* POSIX.1-2017
* IEEE Std 1003.1-2017
* The Open Group Technical Standard Base Specifications, Issue 7
* The Open Group Base Specifications Issue 7, 2018 Edition

and no longer has visible "Single Unix Specification" branding at all.
However, the downloadable tarballs at
http://pubs.opengroup.org/onlinepubs/9699919799/download/
have basename susv4-2018. According to Wikipedia it "incorporates Singles
UNIX Specification TC1 and TC2, and is technically identical to the
2016 edition."

I'd suggest replacing SUSv3 with POSIX.1-2017 or SUSv4 2018 edition
instead, or perhaps replacing SUSv3 with POSIX and clarifying that we
use POSIX to refer to the latest version of the POSIX.1 standard.
