Define enum parse_opt_result before using it in a typedef. This avoids the following compiler warning:
./parse-options.h:53:14: error: ISO C forbids forward references to 'enum' types [-Werror,-Wpedantic]
typedef enum parse_opt_result parse_opt_ll_cb(struct parse_opt_ctx_t *ctx,
^While GCC and Clang both accept such a forward reference by default, other compilers might be less forgiving.
