I'm working on /proc/devices, but upon comparing to Linux[1], I
noticed some differences in character device numbering:

* /dev/tty
Linux is 5,0, Cygwin is 3,0

* /dev/tty[N]
Linux is 4,[N], Cygwin 136,N (major 136 is /dev/pts/N on Linux)

* /dev/console
Linux is 5,1, Cygwin is 3,0 (same as /dev/tty !)

* /dev/ttyS[N]
Linux is 4,[N+64], Cygwin is 117,[N]

Why these differences?
