Glad you got there.

You can always 'force' the function to use whichever version you actually want, by using a 'cast'. So:
Code:

float fred;

    fred=1000.0;

    set_pwm1_duty((int8)(fred/4));


Will force the 'int8 ' version of the function to be used, even though you are handing the function a 'float' (which will always default to using the int16 version - code always uses the _highest_ type from those available if a type doesn't actually fit the choices).
