5712         * f95-lang.c (g95_mark_addressable): Fix prototype to match
5713         the langhook.  Fix 'return's accordingly.

5720         is set.
5721

5723         Patch from Arnaud
5724         * resolve.c (resolve_symbol): Assumed shape arrays must be dummy
5725         arguments.  Also make sure that if a symbol is marked INTRINSIC,

5727         (check_conflict): Make EXTERNAL and DIMENSION attributes conflict.
5728         Do not allow PROCEDURES to have the SAVE, POINTER, TARGET,
5729         ALLOCATABLE, RESULT, IN_NAMESPACE, OPTIONAL or FUNCTION attribute.
