True the warning is irksome, however what bothers me more is why isn't
this caught by -Werror in stage2/3 ?

I can only trigger it using gcc-3.4 with optimization turned on.  So
it's not shown during stage1 in a 3-stage bootstrap.  It only appears
for me using plain "make" using 3.4.

Would you please consider filing a PR about the failure on mainline
(and maybe 4.0?) to emit a diagnostic for this case?  It seems to be a
regression.
