 *
 * VARIABLES
 *	as		The assembler command.
 *			Not altered if already defined.
 *	as_flags	Options to pass the assembler command.
 *			Not altered if already defined.
 *			The default is empty.
 *	as_src		Assembler source files in the current directory.
 *	dot_src		Source files constructable in the current directory
 *			(unioned with existing setting, if necessary).
 *	dot_obj		Object files constructable in the current directory
