0.8.2.34:
	Merge patch from Brian Mastenbrook for better dlfoo handling
	on Darwin (plus more-likely cpp options, add boilerplate)
	... reindent to 4 spaces;
	ASSQ patch from observation by PFD sbcl-devel 2003-08-16
	... (NOT (NULL PAIR)) plus explanatory comment;
	Pragmatism: since not all lisps implement arrays with NIL
	specialized-array-element-type, our cross-compiler version needs
	to be more robust.  Symptoms: building sbcl/ppc from openmcl loses
	in cold-init; sbcl/sparc from sbcl-0.7.x hangs in cross-compiler
	compilation of STRING
	... since we don't need any (ARRAY NIL)s to cross-compile SBCL,
		the answer to SIMPLE-ARRAY-NIL-P for constant-folding
		purposes in the cross-compiler is always NIL.
