Error compiling Fibonacci example

[jthomas08]

I downloaded c source from here and ran the Fibonacci example in chapter 24 on calls and functions and got compile time errors: [line 3] Error at '(': Expect ';' after return value. [line 6] Error at '(': Expect ';' after variable declaration. [line 7] Error at '(': Expect ';' after value. [line 8] Error at '(': Expect ';' after value.

any ideas?
