	    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).
	    * doc/config.guess.1: Regenerate.

	    From: 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.
