It's a bit difficult to say why there are warnings when you
neither tell what the warning are nor show the types of the
arguments you pass to fl_set_form_callback(). Is 'thisone' a
FL_FORM pointer and 'LogState' the name of a void returning
function that has a FL_OBJECT and a void pointer as its only
arguments (and is defined or at least declared before)?
