I had some trouble compiling ispell 3.1.20, and noticed that the kernel
headers define these only for certain platforms. I'm using libc 2.0.5,
for which these definitions come from the kernel headers, and my platform
is one of the poor stepdaughters:

% grep -w TIOCSETP `find /usr/src/linux/include -type f`
/usr/src/linux/include/asm-mips/ioctls.h:#define TIOCSETP (tIOC |
9)
/usr/src/linux/include/asm-mips/ioctls.h:#define TIOCSETN (tIOC |
10) /* TIOCSETP wo flush */
/usr/src/linux/include/asm-alpha/ioctls.h:#define TIOCSETP _IOW('t',
9, struct sgttyb)
/usr/src/linux/include/asm-alpha/ioctls.h:#define TIOCSETN _IOW('t',
10, struct sgttyb) /* TIOCSETP wo flush */
/usr/src/linux/include/asm-sparc/ioctls.h:#define TIOCSETP __TIOCSETP
/usr/src/linux/include/asm-ppc/termios.h:#define TIOCSETP _IOW('t',
9, struct sgttyb)
/usr/src/linux/include/asm-ppc/termios.h:#define TIOCSETN _IOW('t',
10, struct sgttyb) /* TIOCSETP wo flush */
/usr/src/linux/include/asm-ppc/ioctls.h:#define TIOCSETP _IOW('t',

/usr/src/linux/include/asm-ppc/ioctls.h:#define TIOCSETN _IOW('t',
10, struct sgttyb) /* TIOCSETP wo flush */
/usr/src/linux/include/asm-sparc64/ioctls.h:#define TIOCSETP __TIOCSETP

% grep -w TIOCSETN `find /usr/src/linux/include -type f`
