In C, to pass the pointer of an object to a function (or to take the address
of an object with the & operator in general), that object must be "static" or
"auto", not "register"!  In most C compilers, the default storage class is
"auto" (given that you don't explicitly declare a storage class).  But in C-
Power, the default storage class is "register".  To solve your problem (or
at least make it manageable - I didn't check it out, just saw the obvious),
either declare any variables which you use & with to be explicitly auto as in:
	auto char x;
instead of:
	char x;
Or, even simpler, but it will make your programs run slower, use the "-a"
option when invoking the compiler - this will force the default storage class
to become "auto"; then if it works, go back and declare all variables which
can be "register" to explicitly be so.
Hope this solves your problem.

Sincerely,
Frank Prindle
