Simple module, but won't build

I am taking a driver I wrote for a 2.4.2 kernel, built with 2.95.x
compiler and trying to port it to 82xx from 8xx and use the new ELDK.

Since it is so simple, it just writes to a mem mapped I/O port to set
some LED's on/off, I assumed it would be pretty simple. But alas, that
was probably a bad assumption on my part.

The main module includes the following:

   linux/module.h
   linux/fs.h
   asm/io.h
   asm/uaccess.h

in that order.

I have grep'ed for CONFIG_KERNEL_START and CONFIG_TASK_SIZE and the only
place I can find them defined is in the kernel source .config (and
default config files for each board). Not in any of the header files.

Maybe I am sposed to #define them myself - I tried that and it worked -
but would like a more automagic solution if there is one!

Command line options are:

   -D__KERNEL__ -DMODULE -Wall -fno-builtins -O -c

Sorry, yes.
