57 ?X: This unit tries to remember what we did last time we ran Configure, mostly
58 ?X: for the sake of setting defaults.
60 ?MAKE:Oldconfig hint myuname osname osvers: Instruct Myread uname \
61 Checkcc Mksymlinks run \
62 sh awk sed test cat rm lns tr n c contains Loc Options Tr src trnl ln
63 ?MAKE: -pick wipe $@ %<
65 ?S: The output of 'uname -a' if available, otherwise the hostname. On Xenix,
66 ?S: pseudo variables assignments in the output are stripped, thank you. The
67 ?S: whole thing is then lower-cased.
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.
