Unfortunately, that doesn't work out. Leaving out the petty warnings,
here's what appears:

infundibulum @ /home/aaron/ephem > make
cc -O  -c io.c
io.c:65: storage size of `orig_tio' isn't known [that's struct termio orig_tio]
io.c: In function `byetty':
io.c:190: `TCSETA' undeclared (first use this function)
 [as in: ioctl (0, TCSETA, &orig_tio);]
io.c: In function `setuptty':
io.c:255: storage size of `tio' isn't known
io.c:257: `TCGETA' undeclared (first use this function)
io.c:264: `TCSETA' undeclared (first use this function)
*** Error code 1

Stop.

So I tried adding
#define termio termios
#define TCGETA TIOCGETA
#define TCSETA TIOCSETA
Result: program compiles, but still doesn't work properly.

I should perhaps mention that I'm running this program in an xterm, 
not in dt or console IO.

Just wouldn't be the same, I guess. :) Thought there might be
an easy answer.

Unless someone has a clear idea what's going on, I'm going to drop the 
matter. It wasn't that important to me. One of these days I'll learn
something about these IO functions, but I don't need to right now.
