13 | ?RCS: patch61: replaced .a with $_a all over the place | |
14 | ?RCS: patch61: likewise for .o replaced by $_o | |
15 | ?RCS: patch61: now uses the ar located by Loc.U | |

18 | ?RCS: patch45: allows hint files to specify their own value for 'ranlib' | |

37 | ?S: This variable is set to the pathname of the ranlib program, if it is | |

45 | ?X: Some systems (like MIPS) complain when running ar... Others like Ultrix | |
46 | ?X: need an explicit 'ar ts' to add the table of contents. | |
47 | ?X: Still others like Linux run ar ts successfully, but still need ranlib. | |
48 | ?X: This set of tests seems the minimum necessary to check out Linux. | |
49 | ?X: We need to explicitly put the entries in out-of-order so that Sun's ld | |
50 | ?X: will fail. (Otherwise it complains, but gives an exit status of 0.) | |
