Recursive Fortran subroutines and interfaces

Do I need to define an interface for recursive Fortran95 (and above) subroutines? In a library, does it make a difference if the subroutine is exported to the user?

RECURSIVE is not an attribute that requires an explicit interface, as it doesn't affect how the procedure is called. For more information on explicit interfaces, see an article I wrote a while back on the topic: https://software.intel.com/en-us/blogs/2012/01/05/doctor-fortran-gets-explicit-again
