`configure' knows nothing about those options but just stores
them as given, and only extmk.rb and extconf.rb's know about
them.

Followings are all of *_config options used in 1.7 standard
extension libraries.  They should be documented somewhere.

$ ruby -C ~/src/ruby/1.7 -e 'Dir["ext/**/extconf.rb"].sort.each {|n|
  (l=open(n){|f|f.grep(/\B_config\b/)})[0] and print n,([":\n"]+l).join("\t")
}'
ext/curses/extconf.rb:
	dir_config('curses')
	dir_config('ncurses')
	dir_config('termcap')
ext/dbm/extconf.rb:
	dir_config("dbm")
	dblib = with_config("dbm-type", nil)
ext/dl/extconf.rb:
	$with_type_char  = enable_config("type-char", $with_type_char)
	$with_type_short = enable_config("type-short", $with_type_short)
	$with_type_float = enable_config("type-float", $with_type_float)
	$with_asm        = enable_config("asm", $with_asm)
	args = with_config("args")
ext/gdbm/extconf.rb:
	dir_config("gdbm")
ext/iconv/extconf.rb:
	dir_config("iconv")
ext/readline/extconf.rb:
	dir_config("readline")
ext/socket/extconf.rb:
	if enable_config("ipv6", false)
	    $ipv6lib=with_config("ipv6-lib", nil)
	    $ipv6libdir=with_config("ipv6-libdir", nil)
	if not enable_config("wide-getaddrinfo", false) and try_run(<<EOF)
	case with_config("lookup-order-hack", "UNSPEC")
	  if ENV["SOCKS_SERVER"] or enable_config("socks", false)
ext/tcltklib/extconf.rb:
	dir_config("tk")
	dir_config("tcl")
	dir_config("X11")
	tklib = with_config("tklib")
	tcllib = with_config("tcllib")
	stubs = enable_config("tcltk_stubs") || with_config("tcltk_stubs")
