I currently use gcc-3.4.6, and current net-next-2.6 doesnt compile for me
(but linux-2.6 does compile properly so I just know this is already fixed upstream)

  UPD     include/linux/compile.h
  CC      init/version.o
  LD      init/built-in.o
  LD      .tmp_vmlinux1
drivers/built-in.o(.text+0x86b17): In function `igdng_compute_m_n':
: undefined reference to `__udivdi3'
drivers/built-in.o(.init.text+0x3c44): In function `con_init':
: undefined reference to `.L1443'
make: *** [.tmp_vmlinux1] Erreur 1

No problem with gcc-4.4.0
