+       * trans-expr.c (gfc_conv_variable): A character expression with
+       the VALUE attribute needs an address expression; otherwise all
+       other expressions with this attribute must not be dereferenced.
+       (gfc_conv_function_call): Pass expressions with the VALUE
+       attribute by value, using gfc_conv_expr.
+       * symbol.c (check_conflict): Add strings for INTENT OUT, INOUT
+       and VALUE.  Apply all the constraints associated with the VALUE
+       attribute.
+       (gfc_add_value): New function.
+       (gfc_copy_attr): Call it for VALUE attribute.
+       * decl.c (match_attr_spec): Include the VALUE attribute.
+       (gfc_match_value): New function.
+       * dump-parse-tree.c (gfc_show_attr): Include VALUE.
+       * gfortran.h : Add value to the symbol_attribute structure and
+       add a prototype for gfc_add_value
+       * module.c (mio_internal_string): Include AB_VALUE in enum.
+       (attr_bits): Provide the VALUE string for it.
+       (mio_symbol_attribute): Read or apply the VLUE attribute.
+       * trans-types.c (gfc_sym_type): Variables with the VLAUE
+       attribute are not passed by reference!
+       * resolve.c (was_declared): Add value to those that return 1.
+       (resolve_symbol): Value attribute requires dummy attribute.
+       * match.h : Add prototype for gfc_match_public.
