57 ?X: This unit tries to remember what we did last time we ran Configure, mostly
58 ?X: for the sake of setting defaults.

65 ?S: The output of 'uname -a' if available, otherwise the hostname.
66 ?S: The whole thing is then lower-cased and slashes and single quotes are
70 ?S: Gives the type of hints used for previous answers. May be one of
71 ?S: "default", "recommended" or "previous".
74 ?S: This variable contains the operating system name (e.g. sunos,
75 ?S: solaris, hpux, etc.). It can be useful later on for setting
76 ?S: defaults. Any spaces are replaced with underscores. It is set
77 ?S: to a null string if we can't figure it out.
80 ?S: This variable contains the operating system version (e.g.
81 ?S: 4.1.3, 5.2, etc.). It is primarily used for helping select
82 ?S: an appropriate hints file, but might be useful elsewhere for
83 ?S: setting defaults. It is set to '' if we can't figure it out.
84 ?S: We try to be flexible about how much of the version number
85 ?S: to keep, e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the
86 ?S: same for this package, hints files might just be os_4.0 or
87 ?S: os_4.1, etc., not keeping separate files for each little release.
90 ?C: This symbol contains the name of the operating system, as determined
91 ?C: by Configure. You shouldn't rely on it too much; the specific
92 ?C: feature tests from Configure are generally more reliable.
95 ?C: This symbol contains the version of the operating system, as determined
96 ?C: by Configure. You shouldn't rely on it too much; the specific
97 ?C: feature tests from Configure are generally more reliable.

579 You may give one or more space-separated answers, or "none" if appropriate.
580 If you have a handcrafted Policy.sh file or a Policy.sh file generated by a
581 previous run of Configure, you may specify it as well as or instead of
582 OS-specific hints. If hints are provided for your OS, you should use them:
583 although Perl can probably be built without hints on many platforms, using
584 hints often improve performance and may enable features that Configure can't
585 set up on its own. If there are no hints that match your OS, specify "none";
586 DO NOT give a wrong version or a wrong OS.
