That's a good start ... I wish I would have a OS/X machine available to
play around with it there a little.

Is that something a maintainer does or left up to the end user ? The
nice thing about the gnulib setup is that (a) it's very easy for a
maintainer to pull in gnulib (happens when you run autogen.sh) and (b)
gnulib sources are included in the dist tarball, so that endusers don't
even need to be aware of the package using gnulib.

I'd definitely like to get a better feel for what is needed there before
switching to ustr. (And with the summit coming up, it's definitely not
happening this week :( )
