[Xen-devel] linux-2.6.18-xen.hg compilation issue with gcc 4.3

[Guillaume Rousse <Guillaume.Rousse@xxxxxxxx>]

Hello.

The linux-2.6.18-xen.hg kernel fails to build with gcc 4.3, in linking 
stage:
arch/i386/kernel/built-in.o: In function `sync_xen_wallclock':
time-xen.c:(.text+0x6141): undefined reference to `__udivdi3'
time-xen.c:(.text+0x618a): undefined reference to `__udivdi3'
arch/i386/kernel/built-in.o: In function `do_settimeofday':
(.text+0x63bd): undefined reference to `__udivdi3'
arch/i386/kernel/built-in.o: In function `do_settimeofday':
(.text+0x640b): undefined reference to `__udivdi3'
arch/i386/kernel/built-in.o: In function `do_settimeofday':
(.text+0x6489): undefined reference to `__udivdi3'
arch/i386/kernel/built-in.o:(.text+0x64d2): more undefined references to 
`__udivdi3' follow
According to LKM, this is a known issue:
http://www.nabble.com/undefined-reference-to-__udivdi3-(gcc-4.3)-td17045078.html

However, I couldn't find any loop susceptible to be wrongly optimised in 
incriminated code (sync_xen_wallclock in arch/i386/kernel/time-xen.c). 
Any hint welcome.
