With the added complexity of this module, especially with the different
code paths taken on the different platforms, it will be useful to have a
unit test module.

I run "make check" of a gnulib testdir of all gnulib on various platforms,
every now and then. If there's a problem on some platform, the unit test
would permit to detect it.
