Log message:
	add an extra pass so that declare_segment can get to the data
	that is in bind_segment, so that the size/alignment of segments
	is always correct; this fixes configure -enable-checking
	This probably also addresses the recurring problem I have had
	where loads in segments were broken because the segment was
	smaller than the load offset, e.g. on OpenBSD/mips64, and
	much was broken. I had been working around by blowing up
	the initial segment size guess. Now we get it right up front.
	
	More work is needed here for the typing/debugging of segments (aka globals).
	Once we turn types back on! (once they don't break things)
	
	add a lot of casts to satisfy configure -enable-checking
	This could use careful review.
	
	configure -enable-checking all good now *except* for static link problem,
	and as such shall be enabled shortly unconditionally, at least
	the checks that don't affect .h files (except static link problem)
	(that's an extra level of checking I haven't tested recently, will soon,
	but might be too slow; as well, we can/should dial this back for release)
