There is no such requirement (save maybe to some extent for Ada), it's 
just that you may get extra warnings using another version, or in stage 1 
of a bootstrap (which deliberately does not use -Werror).  It's the 
build-x-target compiler when build != host that must be the same version 
as the host-x-target compiler you are building, not the build-x-host or 
build-x-build compiler.
