	* sem_ch6.adb, s-htable.ads: Minor reformatting.

2010-10-11  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch4.adb (Analyze_Selected_Component): If the selector is
	invisible in an instantiation, and both the formal and the actual are
	private extensions of the same type, look for the desired component in
	the proper view of the parent type.

2010-10-11  Vincent Celier  <celier@adacore.com>

	* adaint.c (__gnat_number_of_cpus): Add implementation for Solaris,
	AIX, Tru64, Darwin, IRIX and HP-UX.
