Problems compiling kernel-source 4.5

[Gabor Zoltan Csejtey <Gabor.Csejtey@idi.ntnu.no>]

I've downloaded the kernel source 2.4.5-1 version.
If I run make dep I got errors.

from  kernel-source-2.4.5/include/linux/kernel.h

As I see _f is calculated:
#define P 22 + sizeof(short) - 3 * sizeof(long) - sizeof(int)
        char _f[P > 0 ? P : 0];         /* Padding: libc5 uses this.. */
#undef P

I have sparc II ULtra 10 machine. Debian testing upgraded.

PS.
Here's the messages what I got.
