ok, currently I have:
[root@localhost linux-2.4.20-18.9]# ls ../linux-2.4.20-8/
include/linux/modules/

processor.stamp  processor.ver

stamp is 0 size (ok) and ver has a line about acpi. I don't know why
these only are here, but essentially there is nobody in there...

On the contrary I am currently trying to compile the newer .20-18.9
kernel and there indeed there is a galaxy of such pairs .stamp .ver.

Let see, what you are saying is that maybe I recompiled the kernel with
all these syms present in include/linux/modules/ dir. As a result,
everything went fine (kernel and modules compilation + installlation +
boot and use) but it would impede somehow the compilation of 3rd party
source, even if now these symbols have disappeared. Am I understanding
correctly?
In such a case I am a bit surprised that nobody has mentioned it in the
doc I read, but I believe you :)

I am going to try removing these from the newer kernel directory and see
if this solve my compilation problem. 

Let me know if I understood correctly you point, in which case I will
recompile the 2.4.20-8 kernel as well.
