How about this: /* Suppress unused-variable warnings by "using" E. */ static int yyunused; #define YYUSE(e) yyunused = (int*) &(e) && yyunused
That cast doesn't seem to serve much purpose. I'm not sure why I left it.
No unused variables (as long as YYUSE is used somewhere)YYUSE(yyunused) :)
How oxymoronic.Because of yysymprint() at least, I assumed YYUSE() would never go unused. But I guess you never know where code evolution will take you.
