Description of problem:
After installation of RH 9 and of the acpi patch, the kernel does not compile.

Here is what I do : I bought a brand new HP Pavillion ze 5400 and I struggle
install RH 9.0 on it. Therefore I follow the instructions given on this Web page:
http://home.elp.rr.com/mcghees/ze5470us.htm

When I compile the kernel image ("make bzImage") after having executed 
make[2]: Entering directory `/usr/src/linux-2.4.20-8/net'

"make dep" successfully, I get the following compilation error :


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
- I installed RH 9.0 (all packages from the 3 CDs of binary
distribution). Therefore, I have the sources of kernel 2.4.20-8 on the
machine. I have kudzu and pcmcia not started.

- I installed the acpi patch (acpi-20021212-2.4.20.diff.gz) that is normally
compatible with the kernel.
- I configured the kernel compilation options  ("make xconfig"):
a/ I chose "Pentium II / Celeron / Pentium Pro" under the processor type and
features button (I have an Intel Celeron 2.2 GHz on the labtop).I selected 'n' n
for Toshiba and Dell Laptop support.  I made sure Local
APIC support on uniprocessors is set to n. 
b/ Under the General setup button,  I selected the ACPI Support button,selected
y for everything except Toshiba Laptop Extras. 
c/ under the FileSystems button, I selected m for NTFS system support
- I started compile the kernel. "Make dep" went OK. But "make bzImage"
went wrong and produced the compilation error.

Then "make dep".

Then "make bzImage".
