No, the code doesn’t redefine “__cplusplus” anywhere.  In each of the two systems (FreeBSD and Mac OS X) that I tested, the compiler is telling me the value of “__cplusplus” (201402L and 199711L, respectively), and it’s telling me where it’s *defined* (not ‘redefined’) - in something called "<built-in>”.

And that’s what I’m reporting.

Again, that’s what I’m doing.
