Disclaimer: I know nothing about Racket extensions.

In C++, if you want to be able to call a function from multiple .cpp
files, you typically put the *declaration* in a header:

  void func1_ext(void);

The definition would still go in a .cpp file:

  void func1_ext(void)
  {
    /*...*/
  }

You typically only put the definition in a header if you want to make an
inline function.  It doesn't seem like you want an inline function here.

Does that help?
