[Xen-devel] [PATCH] the address of 'symbols_addresses' will always evaluate as 'true'

["S.Çağlar Onur" <caglar@xxxxxxxxxxxxx>]

Hi;

Attached patch adds "-Wno-always-true" CFLAGS into xen/arch/powerpc/Rules.mk 
and xen/arch/x86/Rules.mk, else compiling xen with latest gcc-4.2.0 snapshot 
fails, patch is against current xen-3.0.4-testing repo;
