I'd risk say this is a bug in GCC. Or at least a pretty ugly
implementation of something that should be simple.
We can't be compatible with all versions of GCC on what attributes
they support and the compile-time flags that they use. This just
In a way, if you don't want ABI tags, use Clang 3.8 or before. If you
do, use Clang 3.9 or after.
I'm not sure there's a better way of doing this and creating a
compile-time flag just to imitate GCC seems like the wrong way to go,
