Examples of new warnings:

         if ((store_length >= length) || (i > 0)) /* for all parts of end key*/
             ~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~

storage/innobase/include/page0zip.ic:145:24: error: ?: using integer constants in boolean context, the expression will always evaluate to ‘true’ [-Werror=int-in-bool-context]
  ut_ad(rec_size > comp ? REC_N_NEW_EXTRA_BYTES : REC_N_OLD_EXTRA_BYTES);

storage/innobase/data/data0type.cc:224:8: error: this statement may fall through [-Werror=implicit-fallthrough=]
   fputs("DATA_VAR_POINT", stderr);
