Is there a dmd.exe x86_64 out there?

Maybe, Linux is finicky here library wise. Usually both arch binaries 
are required library wise and since Alpine is minimal.. easy to assume.

You're the first in over six months to bring up this issue, so not a 
common requirement ;)

Based on what I read, wineboot handles an instance lifetime e.g. 
restart. So killing of processes and getting mounts in for example.
The link I gave has an example of a program that configures a new 
instance of Wine that is 32bit (since you can't change a 64bit one to 
32bit) which is not the same thing.

Given this information, yeah it might be worthwhile to distribute a 
build of dmd that is 64bit for Windows. But this won't allow you to 
execute the produced programs under Wine. Since you can't execute 32bit 
programs and since you can't really install MSVC or the required 
programs/libraries from Microsoft your stuck there.

So really you want to get this sorted out.
