System: NetBSD skysensor 1.6ZC NetBSD 1.6ZC (GENERIC) #7: Tue Sep 30 21:10:18 JST 2003 smi@nbx1:/work/nb/arch/i386/obj/sys/arch/i386/compile/GENERIC i386
Architecture: armeb
Machine: evbarm
>Description:
	By the change of gcc version to 3.3.1, zao425 build breaks in
- arch/arm/arm32/pmap.c
- arch/evbarm/ixdp425/ixdp425_machdep.c
- arch/arm/xscale/becc_pci.c

>How-To-Repeat:
	do build.sh release, and
	do build.sh kernel=ZAO425
>Fix:
I made modifications like this just adding initializers, or removing
unused variables, it might be not correct, however.
