+
+	config.guess: x86_64-pc-solaris2.11 is not properly recognized
+	config.guess guesses Solaris 11 to run on a 32-bit platform
+	despite Solaris 11 no longer supporting any 32-bit platform.
+
+	See the following code at lines 434 to 445:
+
+	| SUN_ARCH=i386
+	| # If there is a compiler, see if it is configured for 64-bit objects.
+	| # Note that the Sun cc does not turn __LP64__ into 1 like gcc does.
+	| # This test works for both compilers.
+	| if test "$CC_FOR_BUILD" != no_compiler_found; then
+	|     if (echo '#ifdef __amd64'; echo IS_64BIT_ARCH; echo '#endif') | \
+	|         (CCOPTS="" $CC_FOR_BUILD -E - 2>/dev/null) | \
+	|         grep IS_64BIT_ARCH >/dev/null
+	|     then
+	|         SUN_ARCH=x86_64
+	|     fi
+	| fi
+
+	If "cc" is installed, i.e. the Oracle Studio compiler, this one is
+	chosen for $CC_FOR_BUILD.  This compiler, the gcc provided by Oracle
+	and also gcc bootstrapped from sources on that platform with a default
+	configuration will by default generate 32-bit binaries -- even on
+	a 64-bit platform.  And __amd64 will not be defined for compilations
+	targeting a 32-bit platform.  This is different from the corresponding
+	behaviour on GNU/Linux systems where the local platform is targeted by
+	default.
+
+	Thus, as long as you do not add "-m64" or if you have a custom-built
+	gcc which defaults to 64 bit, you will get 32-bit binaries on Solaris
+	despite living on a 64-bit platform.
+
+	* config.guess (i86pc:SunOS:5.*:* || i86xen:SunOS:5.*:*): Adapt the
+	test by adding the "-m64" flag.  This will work properly for Solaris
+	10 as well (the last Solaris release that supported x86 32-bit
+	platforms).

+	2021-08-14  Nick Bowler  <nbowler@draconx.ca>
+
+	config.sub: work around command assignment bug in some shells
+	When combining variable assignments with a shell command, some older
+	shells (notably heirloom-sh and presumably also Solaris 10 /bin/sh)
+	have a bug which causes the assignment to alter the current execution
+	environment whenever the command is a shell built-in.  For example:
+
+	  % dash -c 'x=good; x=bad echo >/dev/null; echo $x'
+	  good
+
+	  % jsh -c 'x=good; x=bad echo >/dev/null; echo $x'
+	  bad
+
+	The config.sub script contains a few commands of the form:
+
+	  IFS=- read ...
+
+	which triggers this bug, causing the IFS assignment to persist for the
+	remainder of the script.  This can cause misbehaviour in certain cases,
+	for example:
+
+	  % jsh config.sub i386-linux-gnu
+	  config.sub: test: unknown operator gnu
+
+	  % jsh config.sub i386-gnu/linux
+	  sed: can't read s|gnu/linux|gnu|: No such file or directory
+	  Invalid configuration `i386-gnu/linux': OS `' not recognized
+
+	* config.sub: Save and restore IFS explicitly to avoid shell bugs.
+	* doc/config.sub.1: Regenerate.

+
+	config.sub: normalize the quoting in the `echo FOO | sed ...`
+	Some cases quote the argument to echo and some do not.  At runtime
+	it probably does not matter because the substituted values will never

+	useful.
+
+	* config.sub: Consistently quote the argument of echo.

+	Remove automatic patch generators
+	These tools have served their purposes and need not be kept outside of
+	the repository history any longer.  This patch as a diff also collects

+
+	config.guess: manual fixups after previous automatic patch
+	The tool could not handle command substitutions that span lines, but
+	fortunately there were only two such substitutions in the script.
+
+	The test for which universe is active on Pyramid is rewritten into a
+	case block because it was the only use of a command substitution as an
+	argument to the test command, which would require quoting.
+
+	* config.guess: Rewrite "if" for Pyramid systems to "case".
+
+	2021-05-26  Jacob Bachmeyer  <jcb@gnu.org>
+
+	config.guess: replace POSIX $( ) with classic ` ` throughout
+	The previous replacement of backticks with POSIX command substitutions
+	was ill-considered and illogical: this script recognizes many archaic
+	machine types that probably never had POSIX shells, therefore it needs
+	to be able to run successfully under pre-POSIX shells.
+
+	This patch was generated using the included GNU Awk program.
+
+	* config.guess: Revert POSIX command substitutions to classic form.
+	* patch-6.gawk: Store the tool that produced the automated patch.
+
+	2021-05-26  Jacob Bachmeyer  <jcb@gnu.org>
+
+	config.guess: manual fixup after previous automated patches
+	This patch provides the special handling for the GNU system.  As these
+	were two small and unique edits, they were not included in the scripts.
+
+	This patch also cleans up other minor issues that must be addressed
+	before reverting to classic command substitutions and updates
+	"shellcheck" directives to account for changes in this script and the
+	change in "shellcheck" towards reporting individual portability issues.
+
+	2021-05-26  Jacob Bachmeyer  <jcb@gnu.org>
+
+	config.guess: automatic fixups after previous automated patch
+	This patch was generated using the following command:
+
+	  sed -i config.guess \
+	      -e '/="[^"]\+"\(-\|$\)/s/="\([^"([:space:])]\+\)"/=\1/' \
+	      -e '/="[^"]\+"[[:alnum:]]/s/="\$\([^([:space:])]\+\)"/=${\1}/' \
+	      -e \
+	'/\$(echo[^|]\+|/s/\([^[:space:]]\)[[:space:]]*|[[:space:]]*sed/\1 | sed/g'
+
+	* config.guess: Remove unneeded quotes in other variable assignments,
+	standardize spacing for "echo ... | sed" substitutions.
+
+	2021-05-26  Jacob Bachmeyer  <jcb@gnu.org>
+
+	config.guess: remove unneeded quotes and factor command substitutions
+	This is further cleanup and simplifies some constructs that can confuse
+	Emacs' syntax highlighting while generally reducing required quoting.
+
+	This patch was generated using the included GNU Awk program.
+
+	* config.guess: Remove unneeded variable quotes and factor out command
+	substitutions when setting GUESS.
+	* patch-3.gawk: Store the tool that produced the automated patch.
+

+
+	config.guess: manual fixups after previous automatic patch
+	* config.guess: Adjust a few "leftover" cases that the tool could not
+	easily recognize and fixes comment indentation in a few other special
+	cases.
+
+	2021-05-25  Jacob Bachmeyer  <jcb@gnu.org>
+
+	config.guess: use intermediate variable with uname results
+	This will allow quoting to be significantly simplified in another
+	pass through the file.
+
+	This patch was generated using the included GNU Awk program.
+
+	* config.guess: Use GUESS variable to hold results of uname analysis.
+	* patch-1.gawk: Store the tool that produced the automated patch.

+
+	config.guess: fix shellcheck warning SC2154
+	While, according to Plan 9 documentation, the environment variable
+	$cputype is set to the name of the kernel's CPU's architecture,
+	shellcheck warns that cputype is referenced but not assigned.
+	Be on the safe side and do not use cputype if it is not defined
+	or empty.
+
+	* config.guess (*:Plan9:*:*): Fix shellcheck warning SC2154.
+
+	2021-05-24  Dmitry V. Levin  <ldv@altlinux.org>
+
+	config.guess: remove redundant quotes in case commands
+	According to the GNU Autoconf Portable Shell Programming manual,
+	the Bourne shell does not systematically split variables and back-quoted
+	expressions, in particular on the right-hand side of assignments and in
+	the argument of 'case'.
+
+	The change is made automatically using the following command:
+	$ sed -E -i 's/(\<case )"(\$[^"]+)"( in\>)/\1\2\3/' config.guess
+
+	* config.guess: Simplify case commands by removing quotes around the
+	argument.

+
+	config.guess: simplify exit status workaround on alphaev67-dec-osf5.1
+	Commit 29865ea8a5622cdd80b7a69a0afa78004b4cd311 introduced an exit trap
+	reset before exiting to avoid a spurious non-zero exit status on
+	alphaev67-dec-osf5.1.  Simplify that code a bit by moving the exit trap
+	reset around.
+
+	* config.guess (alpha:OSF1:*:*): Reset exit trap earlier.
+	* doc/config.guess.1: Regenerate.
