Circular dependency found defining a name like another name

["Lim Hock-Chai" <Lim.Hock-Chai@xxxxxxxxxxxxxxx>]

I'm getting compile error "Circular dependency found defining a name
like another name" when try to compile below.  I can't make any sense
out of this error.  *** Note: This error went away if I remove the
inz(dir) on D spec of myNewDir .
