Having to work around compiler differences is a real world problem. As
has been pointed out before msvc handles function specific optimisations
using intrinsics automatically. GCC and Clang don't so to avoid the
multiple issues cause by having to move things to a different file we
need to work around it. Thankfully macros allow the impact to be
minimised.
