constructor function vs constructor macro

[Masinter.pa@Xerox.ARPA]

On p. 308, it says that defstruct defines a constructor function named
make-name, and talks about the automatically defined
constructor-function. However, on page 357, it says that #S calls the
constructor <macro>. Am I right in assuming that p 357 is wrong, and the
constructor is a function rather than a macro?
