Description

tambryopened on May 6, 2022Issue body actions

In #55064 it was discovered that libc++ ABI version 2 accidentally lost pre-C++11 support. @philnik777 fixed it in 6b257af.

The affected CMake tests were updated to not use C++98. However, if libc++ ABI version 2 doesn't plan to support older language modes CMake needs to be updated to serve an error to users of ABI version 2 when compiling in non-supported modes, rather than failing during compilation.

What is the stance on C++98/03 support for libc++ ABI version 2?
