Just need to see if my changes work for the 2.2.xx kernels patched with rtai.

I suspect that some Makefiles will look for the kernel headers in 
/usr/src/linux-2.4, most won't. But as RedHat had this symlink, I thought it 
best to retain it just in case.

Doing a quick grep of the .def files, I would suggest adding NO_JAVA to your 
make commands.

I added this very quickly one night to get rid of the warning - This should 
be changed to a VERSION > 2.4.15 so that later kernels do not have the same 
trouble. It might be that future kernels will drop malloc.h alltogether.

Oh t**, I think I'd commented that include out to head off a bunch of 
compiler warnings here. I'll have a look at the sourceforge diff logs, and if 
I am guilty, fix it.
