It is not clear why these were originally added. One hypothesis is that an ancient version of MinGW didn't define them. In any case, they appear to now be superfluous, so let's remove them. If nothing else, the buildfarm might offer us clues to their origins. Reviewed-by: Thomas Munro Discussion: https://postgr.es/m/Z4chOKfnthRH71mw%40nathan
