Also macrom.c in my situation (my first try at a patch file attached
below). I'm kinda new to kernel compiling, but I was having the same issue
(more or less) on a Centris 650, 40M RAM, 68040 (with f/p support).
I got the same error there, but also in macrom.c

I assume the conditional compile check proposed by Ed was the right one to
use (since I saw no naysays I assumed it mustn't be horrible).

Thanks,
gene
