>Won't work when mixing with C(++) code and you want a shared C runtime. Which shouldn't be an extremely exotic use case (D plugin as DLL).

You're straw manning.  We're not talking about dropping support for msvcrt.dll,
we're talking about making the default a static library. The developer can
still opt-in to link against msvcrXX.dll, which they would when their software
is going to be deployed with an installer or if they need to interoperate with
C++ binaries. And by the way, DMD is currently only compatible with C++
programs that link against msvcr100.dll, a small subset of the versions of
msvcrXX.dll.  The fact that DMD binaries on windows are only compatible with a
small subset of C++ binaries is a fact that should not be hidden from the
developer.  By making it "opt-in" rather than defaulting to one
specific-version, you're making it easier for developers because now they know
what their binaries are compatible with.

> Anyway, I'm out of this discussion, I think I made my points.

The main point I've gotten from you is that you think it's ok for simple
programs compiled with DMD to not work on other's computers by default.  Right
now this is a fundamental disagreement between us that makes all your other
points moot.
