Well, no, it's for POSIX systems too.  POSIX says that if you clear all
environment variables, the resulting behavior need not conform to POSIX
any more.  See the rationale of the "env" command in the latest POSIX
spec.  This is a fairly recent addition to the POSIX spec, and it came
up because of some systems that fail to conform to POSIX unless certain
environment variables are set correctly (it's not just POSIXLY_CORRECT
and Linux; it's other stuff).
