[QST] cpp11.cu compiles with c++14

[chsigg]

I think cpp11.cu should be comparing against (from https://gcc.gnu.org/onlinedocs/cpp/Standard-Predefined-Macros.html) 201103L.

Although I vaguely remember that with a newer compiler, it can be difficult to test old standard compatibility. So maybe it just needs a comment that this is the best workable solution.

Feel free to close without comment, I just noticed the discrepancy between the code and the error message below.
