The documentation says this library targets c++ 11, but it uses unique_ptr<T, deleter>, which was introduced in c++14. Which I noticed because the ratty toolchain for my targeted device is stuck on c++11.

Is this considered a bug, and should I open a ticket?

I tried #define unique_ptr shared_ptr, but shared_ptr doesn't have a deleter template parameter option. Same with auto_ptr.
Any other workaround suggestions that preferably don't involve hacking the json.hpp?

I don't actually need custom allocators; is there a way to create my own std::unique_ptr<T, junk> that just aliases auto_ptr?
