There's still plently of people using libc 5 (and for good
reasons!). I think there's even people using libc 4. If 2.3 were to
introduce a 64 bit dev_t, it would stuff these people up, I think.
While you could perhaps argue that libc 4 is so ancient that it
doesn't have to be supported with kernel 2.3, I don't think libc 5
compatibility should be broken yet.
