This is nonsense.

I am not speaking from a "compiler implementors point of view".

If, from ANYONE's point of view, there is a cycle in the dependency
graph, then there exists NO fully correct initialization sequence.

Period.

And, if I may be so bold, from a software engineer's point of view,
if there exists such a cycle, then the project is badly designed.  It
is a sign of layering violations or poor problem decomposition.  If
the application works at all, it will be by accident.  

If a developer cannot be bothered to create the dependency graph at
all, merely by linking each library to the libraries it uses, it is
not a matter of complexity, it is a matter of laziness.

I have no sympathy.
