As you say, gcc is getting stricter.  There is an increasing effort to
warn about things which ISO C describes as implementation defined or
as undefined.  (I don't personally know what ISO C says about this
type of thing, but I do know that the gcc team, particularly Joseph
Myers, is trying to make gcc conform to the standard as closely as
possible.)
