As Paul now uses Git (I know, for experimental purposes), it would not 
be too difficult to set up some build checks with Travis. Anytime he 
pushes something, it can sanity checks. For example, run "make" and see 
whether it compiles (which would for example have caught the pacificnew 
issue). I'd be more than happy to have a look at this, and prepare a PR 
for it. If anybody has other sanity checks that can be automatically 
run, that would make it less likely that "trivial" issues like this 
would crop up.

Paul, I also think it would be good if you could "git tag" each release 
when you make them, instead of just having the "Release 2018b" text.

cheers,
Derick
