Problems building the eepro100 driver on Red Hat Linux 9

I can't get the eepro100 driver downloaded from ftp.scyld.com to build
on Red Hat Linux 9 (with the kernel-source-2.4.20-8 package installed).
I receive the following error:

#error Modules should never use kernel-headers system headers,
#error but rather headers from an appropriate kernel-source package.
#error Change -I/usr/src/linux/include (or similar) to
#error -I/lib/modules/$(uname -r)/build/include
#error to build against the currently-running kernel.

I've tried both the suggested build command:

gcc -DMODULE -D__KERNEL__ -DEXPORT_SYMTAB -O6 -c driver.c

And a command specifying a different include path:

gcc -I/lib/modules/$(uname -r)/build/include -DMODULE -D__KERNEL__ -DEXPORT_SYMTAB -O6 -c driver.c

I get the error, even after I figured out that I needed kern_compat.h.

This error isn't mentioned in Google or in the mailing list archives.
Can anyone help me get this driver built?  I'm convinced it will make
my currently non-functioning Ethernet cards work.

Regs,
