I just now came across this snippet in font.c:
Lisp_Object alters
= Fassoc_string (val, Vface_alternative_font_family_alist,
#ifndef HAVE_NS
Qt
#else
Qnil
#endif
);
Is there a good reason why the entries in
face-alternative-font-family-alist need to be case sensitive on NS when
they are not on other platforms?

For reference, this is bug #2526.

Font family matching is case sensitive in the API used
by the NS font driver.

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.

Logically, this behavior is consistent with family names being case
sensitive -- the user customizing face-font-family-alternatives may
want to specify different alternative lists for different family
names, even if they differ only in their case. But practically, I
doubt the situation will come up in that way -- so we might as well
remove the ifdef to streamline the code if that is best.
