The build problem on BSD is known and being worked on [1]. I was going
to install FreeBSD to examine it closey, but got distracted.

The AIX problem is from d1dd94b308 (Do not print 'dangling' for
cat-file in case of ambiguity - 2019-01-17). Apparently AIX compiler
is a bit picky about enum being a strong or weak type. I like this
compiler. The below patch should do.

The test failures on NetBSD and Solaris/Sparc, not sure if we can do
anything without test logs or access to these systems.
