	* lib-xref.adb: (Hash): Avoid use of 'Mod attribute, because old
	compilers don't understand it.

2011-09-02  Gary Dismukes  <dismukes@adacore.com>

	* exp_attr.adb (Expand_N_Attribute_Reference): Pass the
	underlying subtype rather than its base type on the call to
	Build_Record_Or_Elementary_Input_Function, so that any
	constraints on a discriminated subtype will be available for
	doing the check required by AI05-0192.
	* exp_strm.adb (Build_Record_Or_Elementary_Input_Function):
	If the prefix subtype of the 'Input attribute is a constrained
	discriminated subtype, then check each constrained discriminant value
	against the corresponding value read from the stream.
