Subject: test12-pre5 does not compile

I compile dummy.c into the kernel; make bzImage stops with:
gcc -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -fno-strict-aliasing -pipe -march=i686 -malign-functions=4 -c -o dummy.o dummy.c
dummy.c: In function `dummy_init_module':
dummy.c:103: invalid type argument of `->'
make[3]: *** [dummy.o] Error 1
make[3]: Leaving directory `/usr/src/linux-2.4.0-test12-pre5/drivers/net'
make[2]: *** [first_rule] Error 2

Known bug. They say the fix is in Linus's patch queue.
