2842 global symbol, creat one if none exists and emit
2843 error if there is a clash.

2846 the function can be called from resolve.c.

2849 already defined or if references were to another type.

2854 gfc_conv_function_call that coverts an expression for an aliased
2855 component reference to a derived type array into a temporary array
2856 of the same type as the component. The temporary is passed as an
2857 actual argument for the procedure call and is copied back to the
2858 derived type after the call.

2860 that is followed by a component reference.
