Is there a dmd.exe x86_64 out there?

We need to see any errors produced from Wine.
It is known that dmd does run under it. Which means something is wrong 
with your setup.

As I said about x86_64 being backwards compatible with x86 (you can even 
run old 386 programs on a modern day cpu, go figure) so that isn't the 
problem.

The reason why we do not provide a dmd compiled for 64bit is simply, 
32bit works in pretty much all cases. The cases it doesn't involve very 
large code bases being compiled.

The only platform this may not be true for is OSX where 32bit is long 
dead globally and 64bit is the only option. Sadly Windows and Linux 
still have 32bit cpus common in the last 10 years.

I just had a look into Wine, I'm not sure if this helps[0].
Right now you're not creating a new Wine environment or configuring it.
Otherwise, can you change over to a 32bit image instead of 64bit alpine? 
That probably will also fix it.
