The file "kernel.h" is required when Inform is compiled on an Acorn
Archimedes. I recommend that you go to line 45 of "headers.h" and
change "#define GRAHAM" to "#define UNIX". When I do this, Inform
compiles fine under both SunOS and Ultrix. If you're compiling under
Linux, then use "#define LINUX" instead.
