On Linux systems with glibc, DEV_BSIZE defines the sector size for the Linux kernel, which is 512 since the beginning of time --- and which we can't really change without breaking a huge amount of kernel code. Some non-glibc C libraries, may not define DEV_BSIZE; if it does not exist, assume that it will be 512.
