M16C compiler error

 Toolchain version 5.20.00


In a file called configs.c there is call to loadParameters():

#include "params.h"

void dummy(void)
bool ret;

ret = loadParameters();


The linker says:
...\configs.r30 : '_loadParameters' value is undefined

I have the following declarations and definitions:

In params.h:

#ifndef PARAMETER_H_
#define PARAMETER_H_

bool "loadParameters" (void);

In file params.c:

#include "parameter.h"

bool loadParameters (void){...}


I have cleaned the project, updated dependencies, added parameters.h to the project though other c files have no problem finding it. Am I missing something obvious?
