	* exp_ch7.adb (Expand_Ctrl_Function_Call): Remove incorrect special
	case for the case of an aggregate component, the attach call for the
	result is actually needed.

	* exp_aggr.adb (Backend_Processing_Possible): Backend processing for
	an array aggregate must be disabled if the component type requires
	controlled actions.

	* exp_ch3.adb: Minor reformatting

	* s-taprop-tru64.adb, s-taprop-vms.adb, s-taprop-linux.adb,
	s-taprop-solaris.adb, s-taprop-irix.adb, s-taprop-hpux-dce.adb,
	s-taprop-posix.adb (Suspend_Until_True): Protect against early wakeup.
