	* prj-makr.adb (Make): Preserve the comments from the original project
	file.
	When removing nodes (attributes Source_Dirs, Source_Files,
	Source_List_File and package Naming), save the comments and attach the
	saved comments to the newly created nodes.
	Do not add a with clause for the naming package if one already exists.
