With string.h I seem to be getting some symbols visibility conflict at
link time:

arch/x86/boot/compressed/misc.c:134: error: conflicting types for ‘memset’
/home/boris/kernel/linux-2.6/arch/x86/include/asm/msr.h:178: error: previous implicit declaration of ‘memset’ was here
make[2]: *** [arch/x86/boot/compressed/misc.o] Error 1
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [arch/x86/boot/compressed/vmlinux] Error 2
make[1]: *** Waiting for unfinished jobs....
make: *** [bzImage] Error 2
make: *** Waiting for unfinished jobs....

Will look more deeply into it tomorrow.
