+       * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
+       not loc->end, since loc->end might contain garbage and this leads
+       to undefined behavior on some platforms.
+       (id_loc, token_start): Use (IF_LINTed) initial values that do not
+       depend on *loc, so that the reader doesn't give the the false
+       impression that *loc is initialized.
+       (<INITIAL>"%%"): Do not bother setting code_start, since its value
+       does not survive the return.
