It was probably in an older version of POSIX (possibly XSI shaded, not
sure). Generally we don't provide full compat with older versions of
the standards, since it turns into a mess of version conditions and
programs using a mix of older stuff are usually better off just with
_DEFAULT_SOURCE (alias _BSD_SOURCE). There are a few exceptions for
stuff that's still widely used like gethostby* that recent standards
removed, but I'm not sure it would make sense to treat getpass special
like that being that it's a rarely used and IIRC removed a long time
ago.
