[cfe-dev] what libc++ version introduced C++14 delete operators?

[René J.V. Bertin via cfe-dev]

Hi,

I hope this is the right place to ask:

What libc++ release version first had the C++14 new & delete operators (specifically, delete(void*, size_t))? I think they were introduced in svn rev. 229281 .

I'm interested in particular how one can test for presence of these functions, preferably with an actual linking step (aka autoconf test).

Thanks!

René
