The Compiler offers a Preprint directive where a listing with the extension *.I is generated. This listing shows the code after the Preprocessor and should contains the function prototypes. It allows you to verify the header files that are included. If the function prototypes are not in this listing you have perhaps some #defines or other conditional preprocessor statements that make them invisible.
