For posterity, this was misdiagnosed on my part. It turns out the pp
conditionals in MathExtras.h select the GCC-style intrinsics for Clang, even in
MS compat mode (because `_MSC_VER` is consistently checked *after*
`__has_builtin` and friends).
So the problem is really with GCC builtins inside function templates. Here's a
minimal repro:
template <class T>
int myctz(unsigned int value) {
return __builtin_ctz(value);
}
