?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 Mksymlinks run \
	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:.
?C:OSVERS:
?C:	This symbol contains the version 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.

?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.
