	* hostparm.ads (Max_Line_Length): Set to Types.Column_Number'Last - 1,
	which is the absolute maximum length we can support.

	* frontend.adb: For the processing of configuration pragma files,
	remove references to Opt.Max_Line_Length, which is not checked anymore.

	* namet.ads (Name_Buffer): Adjust size to reflect increase on max line
	length.

	* scn.adb, scng.adb:
	Always check line length against the absolute supported maximum,
	Hostparm.Max_Line_Length.

	* stylesw.adb (Set_Style_Check_Options, case M): The maximum supported
	value for the maximum line length is Max_Line_Length (not
	Column_Number'Last).
	Minor error msg update
	(Set_Style_Check_Options): New interface returning error msg
	Minor code reorganization (processing for 'M' was out of alpha order)

	msg.
