ok... and this Iterator is exactly equivalent and the same as previously? There is no other change required anywhere?

[greenscientist]

Seems to work...
I've done Claude's suggestion, it's the only changes to make it compile.

I've tested in transition, accessbility map and route calculations works .

Guessing that with this change the right iterator types is picked up. I've sent the changes upstream, wondering if it will be picked as is.

Which upstream? can you link to that PR to see what the upstream says? And fi there is an upstream, why do we have it here too?

Also, you change client_http.hpp, do you need to change client_https.hpp too? Or they are totally different files?

We do it here since for that project it's customary to copy the simple file into the project. We also have some local modifications I think.

We don't need to change client_https.hpp, it uses the content of client_http.hpp

[tahini]

I you say so!
