  In the manual "Xlib Changes From Release 3 to Release 4" from MIT,
it says:

"The use of 'unix' as a hostname in XOpenDisplay is no longer part of the
 specification; use an empty hostname to obtain the 'best' local connection
 type."

  Does that mean that I should say (xlib:open-display "") to open a
connection to the X Server on my machine?  Is this the case in all
flavors of Lisp?  And most importantly, is this backwards compatible to
R3 and earlier versions of CLX?
