This seems fixed in 4.8: we warn only for line #8. Manu could you please double
check we can close this? (thanks a lot again)

(Nit: the location is off by 2 chars, I think I can easily fix this separately:
build_new_op_1 isn't propagating loc to cp_build_binary_op)

Location fixed for 4.9.0.
If we have reasons to believe the bogus warning is now suppressed only be
chance, let's re-open the bug (or move the discussion to 38470?)

------- Comment #7 from manu at gcc dot gnu dot org 2010-02-24 14:16 -------
A simpler version of PR 38470. An idea could be to do some cheap and quick ccp
in the front-end like clang does. The alternative is to move this to the
middle-end, which is rather difficult.
