Sio won't compile in 8.2

[Lars Eighner]

Although the code for sio appears to be in 8.2 (or at least cvsup does not
delete) but it does not compile - apparently owing to a missing tty related
library or a version difference.

Since there does not appear to be any likelihood that uart will be fixed, I
figure I will be stuck in 7.4 forever.  But what does that mean in the not
too distant future when 7.4 is no longer supported?  Is there some way to
prepare for that eventuality?
