While I haven't actually read the gettext docs, I'm pretty sure that
gettext() is defined to preserve errno. It's supposed to be something
that you can drop into existing printf's without thinking, and if
it mangled errno that would certainly not be the case.
If this isn't true, we've got probably hundreds of places that would
need fixing, most of them of the form printf(_(...), strerror(errno)).
