I'm surprised this is necessary, because of BuildDefs::wasm()

[John, 2016/04/05 13:14:08]

the if(constexpr) guard is "weaker" than an #if. The compiler will still parse,
and verify whatever lives within the if-guarded region, even if you have if(0).
I.e.,

if (0) {
  this is invalid C++
}

will not compile (the same goes to if(Zero), where constexpr bool Zero = 0)

[Jim Stichnoth, 2016/04/05 13:18:38]

Oh, right, I forgot about the fact that this code is no longer compilable
because of the #if in the include file.
