Fix those headers by simply casting to the proper type (i.e. what is on the
left of the assignment, if I remember that place rightly).
Another alternative would be to provide an overload of max() taking a long and
a long double.

I still rather fix broken headers and not have makros whos args are evaluated
twice in my programs.
