Not every compiler defines these macros. Let alone, not every compiler properly implements what it advertises. I think it depends on the compiler - the current crop of the latest are pretty good at getting these right. Have MSVC started defining these macros yet?

I see them in VS2017, but I don't know how complete they are. With C++20, the existence of feature test macros and header <version> became mandatory, so both the compiler and the library related macros are there in VS2019 and VS2022.
