Nice. Since users of this module must update their code, I added this mention
in the NEWS file:


Date        Modules         Changes

2007-06-16  lchown          The include file is changed from "lchown.h" to
                            <unistd.h>.

Wouldn't a simple

   #include <unistd.h>
   #undef chown

have done it as well (assuming 'chown' is defined as a function, not as a
macro)?
