[Xen-devel] xen-unstable hg tree doesn't compile: io_apic.c:127: warning: ‘prev’ is used uninitialized in this function

Hi,

the current hg tree doesn't compile on x86.

gcc -O2 -fomit-frame-pointer -DNDEBUG -m32 -march=i686 -Wall 
-Wstrict-prototypes -Wdeclaration-after-statement -nostdinc -fno-builtin 
-fno-common -fno-strict-aliasing -iwithprefix include -Werror 
-Wno-pointer-arith -pipe 
-I/usr/src/xen/xen-unstable.hg-3.0-20060408.1/xen/include 
-I/usr/src/xen/xen-unstable.hg-3.0-20060408.1/xen/include/asm-x86/mach-generic 
-I/usr/src/xen/xen-unstable.hg-3.0-20060408.1/xen/include/asm-x86/mach-default 
-msoft-float -g -D__XEN__ -c io_apic.c -o io_apic.o

I know, this is caused by the Werror flag. Can somebody remove this?

Thanks in advance,

Johnny
