I have brought this up with the vxl folks in the past.  At first, clang rejected it entirely (as it's technically invalid) but later clang allowed it with it a warning.  We'd have to check the list archives, but I don't believe it's fixed in vxl master currently, I think I disabled that warning on my vxl dashboard so they would not be distracted from the many other warnings clang emits, but no one seems to have done much there...

(Worse, vxl doesn't even build, with its default settings, on Lion anymore.)
