Not working patch

This patch implements comment #9.
It fails on proc_decl* and proc_ptr* and cray_pointer_9 unfortunately.  I
investigated the last failure and the outcome is this:  if the dummy arguments
are not present in the procedure symbol, then the array spec and the character
length shall be taken out of it as well, as they contain expressions that may
refer to the dummy arguments.  This makes the approach really too intrusive.
