	* sem_ch5.adb (Analyze_Loop_Statement): Don't check for infinite loop
	warnings unless the loop comes from source, because checking generated
	loops is a waste of time, and makes it harder to debug
	Check_Infinite_Loop_Warning.

	* sem_warn.adb (Check_Infinite_Loop_Warning): If the local variable
	tested in the while loop is a renaming, do not warn. Otherwise, we get
	false alarms, because it's usually renaming something that we can't
	deal with (an indexed component, a global variable, ...).

	* gnat_rm.texi: Fix typo
