	* sysdep.c (__gnat_localtime_tzoff): on Windows, manipulated times are
	unsigned long long. So compare local_time and utc_time before computing
	the difference.

	* sem_ch3.adb (Build_Derived_Private_Type): Insert the declaration
	of the Underlying_Record_View before that of the derived type.

	* exp_ch3.adb (Expand_Record_Extension): Do not special-case types
	with unknown discriminants with regard to the parent subtype.
