We may eventually want -Wno-gnu, but for now let's just handle the warnings as they come. Add -Wno-gnu-variable-sized-type-not-at-end to avoid the warning issued for the initrd_dev_path struct. (Eliminating the warning is preferred to reworking the struct, because the implementation is imported verbatim from Linux.)
