Apparently libc 2.33 deprecates the mallinfo API in favor of the new mallinfo2 API. The API stays nearly the same, only the types in the struct containing the malloc information has changed. Fields in the new API are size_t instead of int. These changes would allow use of mallinfo2 as a build time configuration on systems that have mallinfo2 available.
