I have found a number of places where there were real type
mistakes looking at these warnings.  For example, tests
often assign the return value of sleep() to "status" which is
usually an int. sleep() returns an unsigned int.

IMO BSPs should not add specific warnings but we can't
just delete these -- we need to decide if they become part
of the standard set.
