Okay, you have two problems here.  The first is that you're confusing a
reference with a pointer in the declaration of chng().

void chng( thing &x );

This declaration tells the compiler that chng will accept a reference to
an object of type thing.  However, in your main(), you pass it a pointer
to an object of type thing.  chng(thing&) is not the same function to
the compiler as chng(thing*), so it looks for the latter function.  Not
finding one, nor any way to convert a thing* to a thing&, it gives an
warning.

The second problem you report about cin.getline() is interesting,
because gcc doesn't complain about it at all when I compile your code. 
I originally thought that it might dislike the implicit cast from
unsigned char * to char *, but apparently not.  If you actually get an
error or warning from that line, please report it exactly (see chapter
6.10 of the DJGPP FAQ to learn how to redirect error messages to a
file).

A complaint:  void is not a valid return type for main().  Int is the
only legal ANSI return type, and if you compile with warnings on
('-Wall' flag), the compiler will tell you about it.  If your book or
instructor or sample program says otherwise, it's incorrect.

If you manage to reproduce that error about cin.getline() that you say
happened, please post it here so we can look at it.  FYI, I used gcc
2.8.0 to compile your program; if you are using a different version
(2.7.2.1 or 2.8.1), please tell us.

hth!
