0.8.7.10:

	Various things that are definitely fixes for something
	... s/DO-PENDING-INTERRUPT/RECEIVE-PENDING-INTERRUPT/
		in ppc/system.lisp (as suggested by Lennart Staflin
		sbcl-help 2004-01-01).  This may not fix everything,
		but it's clearly part of *a* problem if not *the*
		problem.
	... define and use a fixnump() static inline function in
		gencgc.c and purify.c, correcting along the way the
		problem in ptrans_code (CSR sbcl-devel 2004-01-08)
	Let's see what difference that makes, shall we?
