+ * snames.adb: Add _stack.
+
+ * snames.ads: Add Name_uStack. Required to allow the expander to

+
+ * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
+ Stack_Address argument.
+ Check that its value is equal to Null_Address because this target does
+ not support the static stack allocation.

+ * exp_dist.adb: Split declaration of asynchronous flag out of
+ Add_RACW_Read_Attribute.
+ Minor reformatting for better alignment with PolyORB version.
+ Store the entity for the asynchronous flag of an RACW, rather than the
+ expression, in the asynchronous flags table. This will allow this flag
+ to be used in other subprograms beside Add_RACW_Read_Attribute.
