I'm pretty sure I have a package for which I'm upstream in Fedora, which
means I represent one of those uses.  (And there's at least INN, for which
I was responsible for introducing strlcpy.)  Based on the previous
conversation, I'll probably eventually end up removing strlcpy entirely in
favor of other techniques, but all my packages that currently use strlcpy
only optionally compile it if it's not in libc.  If it's in libc, the
system version is preferred, since it's presumably more optimized and
possibly safer.

I suspect this is not uncommon among strlcpy users.  (Basically, using
AC_REPLACE_FUNCS.)
