Currently, miss matches of the arguments can only be detected if an explicit
interface is available.
NAG f95 supports run time checking by having a global struct available which
contains information (number of arguments, type/kind of the arguments, pointer
to the function).
Before each procedure call, these are initialized.
In each procedure, they are compared with the settings needed for the dummy
argument. As not all files might be compiled with the same option, one has
additionally to check whether the address of the function matches the address
of the called function.
