[libcxx-commits] [libcxx] [libc++] Remove minimal_cxx11_configuration.pass.cpp (PR #149119)

[Nikolas Klauser via libcxx-commits]

https://github.com/philnik777 created https://github.com/llvm/llvm-project/pull/149119

This test doesn't seem to be very useful. If it is the only test that fails we would just remove the failing parts of the test, and otherwise it doesn't provide any value either, since there will be another test that fails.

-// 3. alias templates
-// 4. defaulted and deleted functions.

-// Some features we don't get and can't be used in extended C++03 mode:
-//
-// 1. noexcept and constexpr
-// 2. Two closing '>' without a space.
