I get a build failure with this one:

   LD      vmlinux.o
   MODPOST vmlinux.o
WARNING: modpost: Found 1 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
   GEN     .version
   CHK     include/linux/compile.h
   UPD     include/linux/compile.h
   CC      init/version.o
   LD      init/built-in.o
   LD      .tmp_vmlinux1
arch/x86/mm/built-in.o(.init.text+0x178a): In function `memtest':
: undefined reference to `__udivdi3'
make[1]: *** [.tmp_vmlinux1] Error 1
make: *** [sub-make] Error 2

I have
	gcc (GCC) 3.3.5 (Debian 1:3.3.5-13)

I know, very old Debian... but the doco says required version is 3.2.

A quick search indicates that this type of failure may be related to
gcc version related optimization. I saw similar reports in linux-next recently.
