What's wrong with this minimal module?

    /* test module */
    #ifndef __KERNEL__
    #define __KERNEL__
    #ifndef MODULE
    #define MODULE
    #endif
    #include <linux/module.h>
    #include <linux/kernel.h>
    #include <linux/malloc.h>
    #ifdef MODULE
    int init_module(void)
    #else
    int test_init(void)
    #endif
    {
            return 0;
    }
    #ifdef MODULE
    void cleanup_module(void)
    {
    }
    #endif
    #endif

both egcs 2.91.66 and redhat's gcc 2.96-85 barf on it:

In file included from /usr/src/linux/include/asm/semaphore.h:11,
                 from /usr/src/linux/include/linux/fs.h:198,

                 from /usr/src/linux/include/linux/mm.h:4,
                 from /usr/src/linux/include/linux/slab.h:14,
                 from /usr/src/linux/include/linux/malloc.h:4,
                 from test.c:11:
/usr/src/linux/include/asm/current.h:4: global register variable follows a function definition
/usr/src/linux/include/asm/current.h:4: warning: call-clobbered register used for global register variable

What have I done wrong?

Thanks,
