Can someone help me find shadow.h?

[John Wolter]

(This is a repost of a previous message which apparently did not make 
it to the net.  My apologies if I appear to be repeating myself.)

Trying to compile xlock (from comp.sources.x) on an SGI IRIS 4D, I 
got an error because of a missing file "shadow.h".  This is a 
SYSTEM V replacement for BSD routines.

Can someone provide?
