When porting things, an error like this usually results from a missing
include file.

>From looking around on the 486 I have at work (which is the same from this
point of view), this code seems to be using old-style tty control. See if
there are configuration options which are more modern, like termios stuff.

Though I don't know if the source is any easier to port, you might try
looking at angband. I really like having a house and a black market. :-)
