--- Comment #2 from Colin Bartlett <colinwb at yahoo dot co.uk> --- I suspected that when compiled programs didn't show the error, but: 1. Is that documented anywhere? It might be useful if that was documented also in choose_multiplier? 2. Is that anyway any reason not to use the correct comparison, unless there is a good reason to use the wrong comparison?
