Yes, that's a disadvantage of the new approach. However, it's common practice with Autoconf to use #define in this case, so we have a lot of experience with that sort of thing. In theory the #define's would break a conforming program that expected a preprocessor expression like "defined intmax_t" to return false, but this sort of thing isn't worth worrying about in practice.
