Kernel Module building problem

Hi,

we are trying to build a kernel module for a PCI card that we use in a Sparc 
Ultra10 under Solaris.

Is there any documentation or examples about building kernel modules for SuSE 
Sparc 7.3 ?

We've been using "Linux Device Drivers" from O'Reilly and have been able to 
develop a module under SuSE 7.3 on a PC, and are having problems building 
this module on a Sparc Ultra 10 platform.

When we compile our source code, we get the following error:

In file included from /lib/modules/2.4.14/build/include/asm/processor.h:23,
                 from /lib/modules/2.4.14/build/include/linux/prefetch.h:13,
                 from /lib/modules/2.4.14/build/include/linux/list.h:6,
                 from /lib/modules/2.4.14/build/include/linux/module.h:12,
                 from base_drv.c:2:
/lib/modules/2.4.14/build/include/asm/page.h:101: global register variable 
follows a function definition
/lib/modules/2.4.14/build/include/asm/page.h:101: warning: call-clobbered 
register used for global register variable
make: *** [base_drv.o] Error 1

Does anyone know if we are we missing some sort of configuration option ?

Any help would be greatly appreciated.

Regards,

Murray Atkinson.

Our Makefile includes this:

CC = /usr/bin/sparc64-linux-gcc -v

CFLAGS = -DBASE_DRV_DEBUG -DKERNEL -D__KERNEL__ -DMODULE \
         -I$(KERNELINC) -O -Wall

KERNELINC = /lib/modules/`uname -r`/build/include

Our /lib/modules/2.4.14/build points to /usr/src/linux-2.4.14.SuSE/
Our /lib/modules/2.4.14/build/include/linux/version.h contains
#define UTS_RELEASE "2.4.14"
#define LINUX_VERSION_CODE 132110
#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))
