llvm-gcc is kind of end-of-life these days (ie: you should probably be using
clang or dragonegg instead) but it looks like you're probably just using an
old version of gcc. While I haven't tried to repro your issue on gcc 4.1, it
doesn't seem to appear on  4.5[.2] (so I guess it was just a new warning
that's been added, and suppressed in the llvm-gcc build, since 4.1)
