Did you test this in a version that was compiled without X support at
all?  If the X support is included, there will be no error even in
"emacs -nw".  But versions without X support don't link fontset.c in
(at least the MS-DOS version doesn't), so if we want to avoid the
error, we need something like (fset 'fontset-font 'ignore) somewhere.
