    	Mostly revert, since it doesn't compile at all on modern
            Linux systems (see sbcl-devel message by "Dave" on 2005-09-23):
            * The decision of whether to use personality() should be completely
              a run-time property, not a compile-time one.
            * Change LISP_FEATURE_LINUX cpp conditionals back to LISP_FEATURE_X86
              or remove them entirely (this is in linux-os.c, so LISP_FEATURE_LINUX
              had better be defined; randomization is only enabled on x86 so
              it's pointless to include the code on other platforms)
            * To solve the problem that was trying to address
              (no <sys/personality.h> on versions of glibc more than three years
              old) define the prototype of personality() in linux-os.c. This
              might not be the optimal solution, but I suppose this isn't the
              right time to experiment...
            The syscall itself is old (goes at least back to kernel 2.0),
            so the system call wrapper should exist even on old versions
            of libc. There should thus be no problems with linking this
            code even on ancient systems.

    	suppressed <sys/personality.h> stuff for old Linux systems (like
    		one of mine) which don't have it
    	(Assuming that I didn't make some weird clerical error, the changes
    		are smaller than they look; I added some extra braces
    		and let emacs regularize the indentation in hopes that
    		it would make it less likely for me to mess up the
    		nesting of if() and #if.)

    	Don't call alloc_sap before fake_foreign_function_call is run,

    	(Lisp-side) allocation will overwrite the SAP object. This may

    	Implement the METAOBJECT class as per AMOP.

    	Make VALIDATE-SUPERCLASS obey the rules.
    	... ah, but we need an additional constraint for CLOS classes
    		to behave: F-S-Cs must have FUNCTION in their CPL, while
    		S-Cs mustn't.  Otherwise you end up with things which
    		are functions but whose type-of isn't subtypep
    		function, and similar disasters.

    	Declassification of INSTANCE and FUNCALLABLE-INSTANCE.
    	It turns out that the classes INSTANCE and
            FUNCALLABLE-INSTANCE, as expressed in instance-pointer-lowtag
    	and funcallable-instance-widetag, are incompatible with the
    	MOP's notion of classes: the types INSTANCE and
    	FUNCALLABLE-INSTANCE are necessarily disjoint (no instance can
    	have a widetag of anything other than instance-header-widetag),
    	but FUNCALLABLE-STANDARD-OBJECT is required to be a subclass of
    	STANDARD-OBJECT, and must therefore have the superclasses of
    	STANDARD-OBJECT among its superclasses.  If INSTANCE is one of
    	those, FUNCALLABLE-INSTANCE cannot be, so F-S-Os would not be of
    	type FUNCALLABLE-INSTANCE (which is wrong); if it is not one of
    	those, then ordinary S-Os would not be of type INSTANCE (which
    	is wrong).  CMUCL, at the time of writing, exhibits type system
    	confusion in this area, as demonstrated by CSR cmucl-imp
    	So, we need to do something else; probably most straightforward
    	to make INSTANCE and FUNCALLABLE-INSTANCE named types, as they
    	are of the same order of specialness as e.g. T -- not quite as
    	special, but almost.  Some hacking later...
    	... the usual type system dance.  Play whack-a-mole with test
    		failures and compilation failures until they all go
    		away.  Primtype, class, typetran, and so on are
    		fiddled with.
    	... somewhat hacky code for determining when a class is subtypep
    		instance / funcallable-instance.
    	... different hard-coded constants for genesis; don't make a
    		special instance-layout, because the instance class is
    	... just to prove we've achieved something, make STANDARD-OBJECT
    		a superclass of FUNCALLABLE-STANDARD-OBJECT.
    		(Supporting METAOBJECT should be straightforward now)
    	... many many new tests, both of the before-xc variety (it's
    		amazing in how many ways I can get the type system
    		wrong) and of the regular form.  Also add some
    		ctor tests that aren't exercised yet.
