I remember finding Microsoft copyright statements in some programs on a Solaris 7 box in 2000 (my memory says /bin/true but some googling reveals it was probably /usr/bin/clear). Some of these programs were implemented as shell scripts and had copyrights from SysV, some of which had come from Xenix.
