Package: libc6-dev Version: 2.1.1-9 <asm/termios.h> includes this definition (amongst others): #define N_AX25 5 if the glibc patches for ax25-utils are to work, this definition must be included in <bits/termios.h>. I don't think it will break anything, but of course I may be wrong. -- Konstantinos Margaritis
