I got the following error with bison 3.7.5 provided by homebrew on macOS Catalina.

parse.y:13337:5: error: implicit declaration of function 'YYUSE' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
    YYUSE(p);
    ^
1 error generated.
make: *** [parse.o] Error 1
make: *** Waiting for unfinished jobs....

I could build with bison-2.3 provided by system toolchain by macOS.

Removed YYUSE [Bug #17582]

Although it was used just to suppress an "unsed argument" warning
in the same manner as other bison-provided functions, it has been
dropped since Bision 3.7.5. And we always suppress that
warnings.
