There are two pull requests [1,2] that would allow C++17 with the line:
There are two stumbling blocks:
1) consensus has been elusive on the default values of compiler.cxx_standard and compiler.c_standard [3,4]
2) there is a concern that the change would negatively impact performance to an unacceptable level .
1) is easy to fix once we decide.
It does not matter to me personally since I do not use the older systems.
I am not sure how to fix 2) since I do not know how to implement caching in the base code.
Please forgive me if this is more information than was requested, but I am hoping to move this pull request forward, and any help would be appreciated.
