sem_ch13.ads, [...] (Adjust_Record_For_Reverse_Bit_Order): Use First/Next_Component_Or_Discriminant 

2007-04-06  Robert Dewar  <dewar@adacore.com>

	* sem_ch13.ads, sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
	Use First/Next_Component_Or_Discriminant
	(Analyze_Record_Representation_Clause):
	Use First/Next_Component_Or_Discriminant
	(Check_Component_Overlap): Use First/Next_Component_Or_Discriminant
	(Analyze_Attribute_Definition_Clause, case Value_Size): Reject
	definition if type is unconstrained.
	(Adjust_Record_For_Reverse_Bit_Order): New procedure
	(Analyze_Attribute_Definition_Clause): Split Is_Abstract flag into
	Is_Abstract_Subprogram and Is_Abstract_Type.
	(Adjust_Record_For_Reverse_Bit_Order): New procedure

	* repinfo.adb (List_Record_Info): Use First/
	Next_Component_Or_Discriminant.

	* style.ads, styleg-c.adb, styleg-c.ads (Check_Array_Attribute_Index):
	New procedure.

	* stylesw.ads, stylesw.adb: Recognize new -gnatyA style switch
	Include -gnatyA in default switches

	* opt.ads: (Warn_On_Non_Local_Exception): New flag
	(Warn_On_Reverse_Bit_Order): New flag
	(Extensions_Allowed): Update the documentation.
	(Warn_On_Questionable_Missing_Parens): Now on by default

	* usage.adb: Add documentation of -gnatw.x/X switches
	Document new -gnatyA style switch
	-gnatq warnings are on by default
