	* make.adb, osint.adb (Add_Lib_Search_Dir): Do not add if dir is
	already in the list.
	This saves system calls when looking for ALI files
	(Scan_Make_Args): The parameter to gnatmake's -D is now converted to an
	absolute PATH (so that the above improvement properly occurs if both
	-D<dir> and -aO<dir> are specified).
