	* sem_ch3.adb (Array_Type_Declaration): move test for type in ALFA
	after index creation; mark unconstrained base array type generated as
	being in/not in ALFA as well
	(Make_Index): mark subtype created as in/not in ALFA
	* sem_ch5.adb (Analyze_Iteration_Scheme): mark entity for iterating
	over a loop as in/not in ALFA, depending on its type and form of loop
	iteration.

2011-08-04  Hristian Kirtchev  <kirtchev@adacore.com>

	* exp_ch7.adb (Build_Object_Declarations): Initialize flag Abort
	directly to False on .NET and JVM.

        * sem_ch3.adb (Constrain_Enumeration, Constrain_Integer): remove
        constraint that subtype must come from source code to be in ALFA, so
        that anonymous subtypes can be in ALFA too.
