3.3.2: conflicting types for sys_ni_syscall

Hi,

I tried to compile 3.3.2 UML on an old pentium III system (3.2.12 was no problem
on this system). With 3.3.2 I get the following error (conflicting types for
"sys_ni_syscall"):

CC      arch/x86/um/sys_call_table_32.o
arch/x86/um/sys_call_table_32.c:44:13: Fehler: In Konflikt stehende Typen für

Here is my .config:

Can you try building the kernel again after a "make mrproper ARCH=um"?

Just tried it... "make ARCH=um" stops with same error message (Archlinux on
PentiumIII, gcc is 4.7.0 20120414 (prerelease)).

Just for the records: 
Here is the solution for the problem (working with gcc 4.7):
