Hi
I can't find how to fix 61347 for alternative modes. I started
with debug mode by providing a forward declaration for safe iterator
type which return to the __distance on normal iterator but gcc still
doesn't consider it as a builtin constant.
I guess the problem might come from compilations options, so is it
that we should simply add a dg-require-normal-mode to have this test
unsupported ? Otherwise any advise to fix this test ?
Making it unsupported is OK. It's only testing that an optimisation
works, but it's OK if it only works in normal mode that's fine.
