Log message:
	multi-part experiment
	
	1: wrap everything
	2: wrap everything taking input socklen_t
	3: wrap everything taking input/output socklen_t
	
	Result is removal of platform-specific socklen_t.
	But at the cost of 200 lines of C (though really
	#1 has nothing to do with socklen_t, #2 is
	/perhaps/ optional, #3 is the real part), perhaps
	this is not worthwhile. I could argue the 200
	lines are simple and not dense, but "lines are lines"?
	Also, this approach is definitely tedious and therefore
	error-prone.
	
	socklen_t so far is 32 bit unsigned everywhere except:
	signed on Cygwin
	size_t on HP-UX, therefore 64 bits on PA64_HPUX/IA64_HPUX
	
	There is something fishy going on in that it seems
	folks were in places passing ADR(INTEGER) here, which
	should fail to compile on everything but Cygwin, esp.
	64 bit platforms. Could be that subranges don't
	define different types in this context?
	UNTRACED REF BITS 32 FOR [0..1]
	same type as UNTRACED REF BITS 32 FOR [0..2]?
	
	I was considering making changes in the clients instead.
	In particular, the in/out socklen_t* is actually only
	used for input, but there are a fair number of clients to visit:
