Log message:
	Crack the Modula-3 renaming code:
	MSETUID <=> S_ISUID
	MSETGID <=> S_ISGID
	MSTICKY <=> S_ISVTX
	
	Now that I figured that out, make them portable too, and give Cygwin
	its values (not sure they do anything there; the ISVTX feature
	is a bit in executable headers, not the file system, and setuid/setgid don't exist
	as far as I know, but Interix apparently offers it somehow).
	
	(See also how Unix.MROWNER == Ustat.S_IREAD == S_IRUSR, if I got those right..)
