I'm not sure that is relevant here. This variable (actually it is 
exposed to lisp as face-font-family-alternatives) is only used when it 
has already been determined that the named font does not exist in the 
system, so for example on other platforms if some lisp code requests the 
font "Sans Serif" or "sans serif" and a font by that name is not 
defined, "helv", "helvetica", "arial" and "fixed" are tried as 
alternatives. But on NS, that list will only be used if the lisp code 
requests that font with matching case.
