No, gpg since 2.1 (i.e. git master) uses the socket S.gpg-agent in the
GNUPGHOME directory by default.  Older versions used a random socket and
conveyed it via an envvar.  The new system is much easier and on Windows
on use for many years.  The only drawback is that it won't work on
certain remote file systems - if that ever turns out to be a problem we
will find a solution.  With 2.0 you may also use the fixed socket name
approach by putting "use-standard-socket" into gpg-agent.conf or a
similar configure option.  My  latest fix to start it correctly is not
in 2.0; could be backported, though

With the latest change you better make sure that GPG_AGENT_INFO is not
set.

My tests showed that it worked really nice.  It will also help to make
the tests suite more robust.
