	* sem_util.ads, sem_util.adb (Defining_Identifier): Adding a formal to
	indicate the needed behavior in case of nodes with errors.

2015-10-27  Ed Schonberg  <schonberg@adacore.com>

	* sem_attr.adb (Eval_Attribute): If the prefix of attribute
	Enum_Rep is an object that is a generated loop variable for an
	element iterator, no folding is possible.
	* sem_res.adb (Resolve_Entity_Name): Do not check for a missing
	initialization in the case of a constant that is an object
	renaming.
	* exp_attr.adb (Expand_N_Attribute_Reference, case Enum_Rep):
	If the prefix is a constant that renames an expression there is
	nothing to evaluate statically.

	* gnatlink.adb: Always delete the response file, even when the
	invocation of gcc to link failed.

	* sem_ch6.adb (Analyze_Subprogram_Body_Helper):
	Do not inherit the SPARK_Mode from the context if it has been
	set already.
	(Build_Subprogram_Declaration): Relocate relevant
	pragmas from the subprogram body to the generated corresponding
	spec. Do not copy aspect SPARK_Mode as this leads to circularity
	in Copy_Separate_Tree. Inherit the attributes that describe
	pragmas Ghost and SPARK_Mode.
	(Move_Pragmas): New routine.
