12 ?RCS: Revision 3.0.1.4 1997/02/28 16:18:18 ram
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
17 ?RCS: Revision 3.0.1.3 1995/01/11 15:33:04 ram
18 ?RCS: patch45: allows hint files to specify their own value for 'ranlib'
20 ?RCS: Revision 3.0.1.2 1994/10/29 16:26:48 ram
21 ?RCS: patch36: now performs a real small compile for accurate checks (ADO)
23 ?RCS: Revision 3.0.1.1 1994/08/29 16:31:17 ram
24 ?RCS: patch32: use cc variable instead of hardwired 'cc' in 1st compile
26 ?RCS: Revision 3.0 1993/08/18 12:09:26 ram
27 ?RCS: Baseline for dist 3.0 netwide release.

32 ?S: This variable is "true" if the components of libraries must be ordered
33 ?S: (with `lorder $* | tsort`) before placing them in an archive. Set to
34 ?S: "false" if ranlib or ar can generate random libraries.
37 ?S: This variable is set to the pathname of the ranlib program, if it is
38 ?S: needed to generate random libraries. Set to ":" if ar can generate
39 ?S: random libraries or if random libraries are not supported
42 : see if ar generates random libraries by itself
44 echo "Checking how to generate random libraries on your machine..." >&4
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.)

84 ?X: Allow hints to specify their own ranlib "script". For instance, on
85 ?X: some NeXT machines, the timestamp put by ranlib is not correct, and this
86 ?X: may raise tedious recompiles for nothing. Therefore, NeXT may add the
87 ?X: ranlib='sleep 5; /bin/ranlib' line in their hints to "fix" that.
