Apparently on OSF we have to define _OSF_SOURCE and _REENTRANT in
order to pick up these decls.

Also, OSF apparently has a gethostbyname_r which isn't like either of
the two other gethostbyname_r's that I've seen.  Finally, the OSF
gethostbyname_r man page says that we should just use gethostbyname
here anyway.

So I recommend somehow arranging so that the gethostbyname_r check
(and possibly other checks as well: look at the OSF man pages, etc) be
avoided in configure.in -- for OSF only.

This isn't pretty, but then these reentrant functions seem to be
especially divergent across platforms.
