linux kernel 2.4.9 acct.c + GCC 3.0.1 => internal compiler error

["peter k." <spam-goes-to-dev-null at gmx dot net>]

hi,
i just updated my gcc from 2.96 to 3.0.1 using the rpms from mandrake cooker
and now i cant compile kernel 2.4.9 anymore (worked fine with 2.96), make
bzImage fails with the following error message:

acct.c: In function `check_free_space':
acct.c:147: Unrecognizable insn:
(insn 335 102 336 (parallel[
            (set (reg/v:SI 2 ecx [44])
                (const_int 0 [0x0]))
            (clobber (reg:CC 17 flags))
        ] ) -1 (insn_list:REG_DEP_ANTI 100 (insn_list:REG_DEP_ANTI 102
(nil)))
    (expr_list:REG_UNUSED (reg:CC 17 flags)
        (nil)))
acct.c:147: Internal compiler error in insn_default_length, at
insn-attrtab.c:223

this error can also be produced by running the following command line (make
bzImage uses the same, i only added -v -save-temps):
[root@HOST2 /usr/src/linux-2.4.9/kernel]#
gcc -v -save-temps -D__KERNEL__ -I/usr/src/linux-2.4.9/include -Wall -Wstric
t-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -f
no-common -pipe -mpreferred-stack-boundary=2 -march=k6    -c -o acct.o
acct.c

gcc -v output [locale problems of my glibc not removed for completeness]:

[root@HOST2 /usr/src/linux-2.4.9]# gcc -v

error / when a fix will be available!
