arch/ppc/kernel/time.c:92: error: static declaration of 'time_offset' follows non-static declaration
include/linux/timex.h:236: error: previous declaration of 'time_offset' was here
make[1]: *** [arch/ppc/kernel/time.o] Error 1

when compiling with gcc-4.0

Taken from
http://user.it.uu.se/~mikpe/linux/patches/2.6/patch-gcc4-fixes-v2-2.6.11
Also removes some obsolete externs that caused problems for Mike
Mike's patch has a bit more stuff in it, but this was enough for me
