OK, I have marked Unixware as not requiring *_r functions. I decided
against optionally using the *_r functions if they exist because it
requires more tests/defines in configure.in, the standard changed the
arguments for some *_r functions over time (from drafts), and there is
no advantage if the libc versions are thread-safe already.
