1.0.26.14: minor portability fixes

1.0.26.14: minor portability fixes
	Motivated by restarting work on a repeatable-xc-fasl project,
	somewhat delayed by Real Life matters...
	... use an explicit TYPE declaration for defined types;
	... don't redefine host functions when building fasls from the
		xc;
	... catch one egregiously bad case of a dead clause in TYPECASE
		(more lurk);
	... don't use host symbols in genesis;
	... define a total order for emitting constants.h.
	Now clisp on my machine, with the current phase of the moon,
	gets as far as dumping the cold core.  More Work Needed.
