Good point. Also, the sort of case where you're likely to be automatically
generating these negative values is also the sort of case where you have
various nice programmatic interfaces, many of which store up all the
warnings. The warnings then have to be freed explicitly, which of course
means that by adding a warning, clients would suddenly start to chew through
piles of memory.
