Actually, I didn’t.  I don’t understand the behavior of clang.
On small examples, ((0)) works perfectly, but in the case of
bison’s own parser, I keep getting errors:

src/parse-gram.c:2848:5: error: code will never be executed [-Werror,-Wunreachable-code]
    goto yyerrorlab;
    ^~~~~~~~~~~~~~~
src/parse-gram.c:2847:8: note: silence by adding parentheses to mark code as explicitly dead
  if ((0))
       ^
       /* DISABLES CODE */ ( )
