I don't have access to a Windows machine for testing, but re-reading
the documentation it looks like the issue is that our noreturn macro
is used after the definition while the MSVC equivalent is used before.
I've removed that for now (and commented about it); it's not as
valuable anyway since it's mostly an indicator for code analysis
(human and machine).
