Let's stick with the functional changes first and worry about the consistency
changes after. Combining them just makes it harder to review the functional

Solaris's /bin/sh doesn't support $() unfortunately. Yes $() is part of POSIX.
 We've had users complain about this not working. Unfortunately that means you
have to split that onto 2 lines. I wasn't thrilled about doing that but
couldn't find a portable way to do it in one line.

We don't always remove work in progress changes that have no impact on end
users. The gtest dependency was added for some work on a C++ binding, which
isn't anywhere close to usable and isn't advertised to anyone.

Agreed about checking results. return without the 1 feels more natural. For
one thing that should preserve the exit value of the last command executed in
the function.

We need to be really careful about updating sqlite. The version you updated to
may be fine. But I know for instance that you don't want to move to a 3.8.x
version. 3.8.x has some poor performance with our wc databases.

I don't really see the problem with us downloading a file not listed on their
website. Their download links seem to be stable, zlib on the other is a much
bigger problem in this respect because they remove the download link we're
using if the version isn't the current version anymore.
