Yes the host GCC since older GCCs don't understand what newer GCCs
support in their diagnostic functions. This is true for doing a
native bootstrap too but since only stage 2 and 3 are compiled with
-Werror, you will not see the warnings turned into errors as the host
GCC already knows what the diagnostic functions support. So for
looking at warnings, it is best to use the same version of the
compiler that you are compiling (until extensible format attributes
are added and supported).
