Exactly. Those fancy feature-test macros are typically more trouble than they're worth. They're mainly of interest to standards nerds, not developers.

I have no specific examples to cite.
Likewise for most developers of portable software, which is why this is a non-issue for them. Feature-test macros don't suffice for portable software, and typically aren't even helpful; they mostly just get in the way..
