0.8.1.50

0.8.1.50
	Alpha fixes before 0.8.2
	... correct type declaration for FOREIGN-SYMBOL-ADDRESS-AS-INTEGER
   	    (add N-MACHINE-WORD-BITS to all backends for this purpose)

        ... correct argument order in the depths of DATA-VECTOR-SET-C/
	    (DEF-SMALL-DATA-VECTOR-FROBS), so Alpha now passes bit
	    array tests

	run-tests.sh now prints the filename of the failing test just
	before stopping, which should save on the effort required to
	misinterpret the backtrace

	delete final full stop from  "  cd tests && sh ./run-tests.sh."
        in make.sh so I can triple-click the line to do exactly that

	commit patch for BASE-CHAR-COMPARE/C that Christophe sent me
	(alpha/char.lisp).  I hope this is what he wanted ...
