On glibc, _LARGEFILE64_SOURCE is defined +if _GNU_SOURCE is defined, so the problem is only seen with musl. + +Since the project uses AC_SYS_LARGEFILE, which from the autoconf doc: +"arrange for 64-bit file offsets, known as large-file support." + +As such, it is safe to assume off_t is 64-bit wide.
