What's missing is probably legacy_stdio_definition.lib that has to be 
added to the linker command line for VS2015 or later. You can verify 
this by checking how dmd invokes the linker by adding -v to the dmd 
command line.

I suspect this happens due to the new VS detection in dmd that hasn't 
been followed up by an appropriate installer update (unfortunately it 
didn't make it into this release). Please try replacing the 
Environment64 section in sc.ini with just this:

[Environment64]
LIB=%@P%\..\lib64
DFLAGS=%DFLAGS% -L/OPT:NOICF
