I looked quickly at that and decide it was more trouble than I was willing
to spend time on at the moment.  But it's a good idea to do.

I'm using GCC 8 on my BSD machine, and it's still throwing some warnings 
(though they're way down from when I opened #24).

I don't usually build with clang at the moment, coz on BSD you can't link in GM 
with Clang, only IM.  I can do that now and then, but it's not the build I'd
use.  I just did it and the warnings that show up in that build are basically
the same ones as we're getting on the Travis OS X build.
