+	supported on this configuration.
+	(getpid): Do not redefine this function on VxWorks when using RTPs

+
+	* decl.c (gnat_to_gnu_entity) <E_Variable>: When allocating storage for
+	a library level mutable variable with an initializer, tell

+	enough for all the values that might be assigned to the variable later
+	on.
