Log message:
	work in progress toward Linux/Unix convergence
	i.e. less header cloning, where possible, on new/recent platforms
	e.g. *_openbsd, sparc64*, sparc32_linux, amd64_*, maybe ppc_linux
	
	openbsd-common used as a small base, 25k vs. the 144k of linuxlibc6
	
	That is, only clone the content within a header that is needed, rather than entire headers
	
	Where headers are #ifdefed into unreadability to define rarely used structs, as is anything
	that has been extended for "large file", considering pushing code into C, e.g. struct stat/dirent/flock.
	
	note that Linux sometimes has architecture-dependence to ease binary compat,
	like Linux/sparc uses Solaris errno and socket values
	
	nothing active here yet
