?X:
?X: This unit tries to remember what we did last time we ran Configure, mostly
?X: for the sake of setting defaults.
?X:
?MAKE:Oldconfig hint myuname osname osvers: Instruct Myread uname Checkcc \
	sh awk sed test cat rm lns tr n c contains Loc Options Tr src trnl ln
?MAKE:	-pick wipe $@ %<
?S:myuname:
?S:	The output of 'uname -a' if available, otherwise the hostname. On Xenix,
?S:	pseudo variables assignments in the output are stripped, thank you. The
?S:	whole thing is then lower-cased.
?S:.
?S:hint:
?S:	Gives the type of hints used for previous answers. May be one of
?S:	"default", "recommended" or "previous".
?S:.
?S:osname:
?S:	This variable contains the operating system name (e.g. sunos,
?S:	solaris, hpux, etc.).  It can be useful later on for setting
?S:	defaults.  Any spaces are replaced with underscores.  It is set
?S:	to a null string if we can't figure it out.
?S:.
?S:osvers:
?S:	This variable contains the operating system version (e.g.
?S:	4.1.3, 5.2, etc.).  It is primarily used for helping select
?S:	an appropriate hints file, but might be useful elsewhere for
?S:	setting defaults.  It is set to '' if we can't figure it out.
?S:	We try to be flexible about how much of the version number
?S:	to keep, e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the
?S:	same for this package, hints files might just be os_4.0 or
?S:	os_4.1, etc., not keeping separate files for each little release.
?S:.
?C:OSNAME:
?C:	This symbol contains the name of the operating system, as determined
?C:	by Configure.  You shouldn't rely on it too much; the specific
?C:	feature tests from Configure are generally more reliable.
?C:.

?X: indentation wrong on purpose--RAM
?X: Leave a white space between first two '(' for ksh. The sub-shell is needed
?X: on some machines to avoid the error message when uname is not found; e.g.
?X: old SUN-OS 3.2 would not execute hostname in (uname -a || hostname). Sigh!
?X: Now not using a subshell but instead $test.
myuname=`$uname -a 2>/dev/null`

?X: Special mention for Xenix, whose 'uname -a' gives us output like this:
?X:  sysname=XENIX
?X:  nodename=whatever
?X:  release=2.3.2 .. etc...
?X: Therefore, we strip all this variable assignment junk and remove all the
?X: new lines to keep the myuname variable sane... --RAM

Configure uses the operating system name and version to set some defaults.
The default value is probably right if the name rings a bell. Otherwise,

	64	?S: The output of 'uname -a' if available, otherwise the hostname. On Xenix,
	65	?S: pseudo variables assignments in the output are stripped, thank you. The
	66	?S: whole thing is then lower-cased.
	67	?S:.

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