Hmm... sounds like a homework question.

A lot has changed since the previous kernels:
~ 1) Header files have moved. A lot of the /linux/include files are not stored there anymore.
~ 2) Much of the architecture has changed with the latest kernels, Please read the associated documents included with the source to find out what has changed.

What happens if you use the makefile. It sounds a little like you want to compile the file all on its own. It doesn't work this way.
You also have to take the 2.4.xx stuff with a grain of salt. The 2.6.xx stuff has changed drastically in many respects.
