Hello Bas,
there is two ways to fix this, you can use the the patch by Steven Cole
(I'll attach it).
Or then you untar the 2.4.21 to another dir and download 2.4.21-ac4
patch and patch the new kernel that you just untarred, and then you copy
$2.4.21-ac4kerneldir/arch/i386/kernel/mpparse.c to
$2.4.22-pre3-ac1kerneldir/arch/i386/kernel/mpparse.c, then it compiles
right. Good luck!
Regards
