0.6.12.3:

0.6.12.3:
	NOTE: This is a slightly screwed-up checkin, which won't
		quite build as is, because the checked-in changes from
		the Alpha port expect various src/code/*types.lisp
		files (e.g. src/code/x86-linux-types.lisp) which
		Daniel Barlow created by hand once and for all. Those
		are in my working directory but I didn't check them in
		because almost immediately, probably 0.6.12.4, I
		expect to rearrange things so that the build
		process generates a types file on every run of
		make.sh. So since CVS add/delete is a little mixed up,
		I thought I'd just skip it, even though it means that
		this version isn't quite buildable unless you grab
		those files from DB's patch.
	merged Daniel Barlow's port to the Alpha CPU sbcl-devel
		2001-05-04
	moved CIRCULAR-LIST-P to early-extensions.lisp (since it
		logically belongs there, and DB's new definition,
		unlike the old one, doesn't have a physical dependence
		on IGNORE-ERRORS which prevents it from being there)
	merged boot-extensions.lisp, early-extensions.lisp, and
		late-extensions.lisp, since there's no longer any
		distinction between the files
	deleted CVS files from sbcl-alpha-extra-files.tar, since
		they were probably an oversight, I think
	also src/compiler/alpha/z050.pdf:-|
	The patch change
			-  (/hexstr arguments)
			+  #!+sb-show (/hexstr arguments)
		shouldn't be necessary because /SHOW, like all the
		/FOO macros, is already conditional on SB-SHOW. So I
		undid this change (and added some comments in
		src/code/show.lisp explaining the intended behavior
		of /FOO macros).
	merged stat_wrapper.c into the relatively new, related
		wrap.c file; deleted stat_wrapper.h since stat wrappers
		seem never intended to be used by C code anyway
	renamed build-tools/ to tools-for-build/ in the interest of
		unambiguous (even painfully unambiguous)
		globally-visible names
	tweaked tests/alien.impure.lisp so that the test uses a
		non-GENCGC-dependent variable (instead of having to
		have the test conditional on #+GENCGC).
