Not so much. There's quite easy if you allow C99, anyway.

typedef struct {
        char *class;
        char *regex;
        int ord;
} Prop;

struct {
        char *Rule;
        RuleFn fn;
        RuleArg arg;
} rules[] = {
        { (Rule[]){ {"WM_CLASS", "foo", 1}, {"WM_NAME", "bar"}, {0}},
          retag, { .s = "baz" } },
};

Or something to that effect. Although a macro to wrap up the
simple cases would probably help.
