Code that should fail with /permissive-. Comments show the current output.

Option /permissive- from MSVC is described at:
https://docs.microsoft.com/en-us/cpp/build/reference/permissive-standards-conformance

MSVC errors out on warnings that break conformance to a standard.

clang-cl generates the warnings, but it does not error out. It produces an
executable.

The excepted behavior is that the build should fail.

Please see attachment for an example.

Platform: Windows 10
Clang-cl version: 11.0.1
MSVC: 19.28.29336 for x64
