Can you not define them yourself in the meantime?

The PR was too late for the beta, but this is the basic change: https://github.com/dlang/druntime/pull/3740/files#diff-5cbe9748431681a766784b1bd997444d58d436a26a345b32397daae478f85c5dR907

Please note that this only supports the C runtimes for VS 2015 or later. If you are using the mingw import libraries, you'll have to switch to the corresponding version, too. Without a VS environment, -mscrtlib=vcruntime140 should do, but the tests had to add

-Lvcruntime140.lib -Llegacy_stdio_definitions.lib -L/NODEFAULTLIB:msvcrt120.lib

on the command line to do that.

// --- compile with -betterC

import core.stdc.stdio;

extern(C):

    }
