A quick survey for C++17 issues in *develop* finds: auto_ptr: ~~~~~~~~~ assign asio (tests do all pass actually with msvc in C++17 mode, but I can't see where/how auto_ptr usage is controlled). ptr_container python (it has a workaround in place, but replies on __cplusplus being set to the correct value, which is not the case for msvc). statechart. typeof (PR submitted) unary/binary_function: ~~~~~~~~~~~~~~~~~~~~ functional (has own workaround that's std lib specific, won't work for everything else?) bimap hash (has own workaround that's std lib specific, won't work for everything else?) Gil ICL MPI bind1st/2nd: ~~~~~~~~~~~~~ GIL Random Spirit Random_shuffle: ~~~~~~~~~~~~~~~ Compute Graph lambda MSM So there's a bit of work to do to fully fix this.
