dmd will now support MS-COFF output with the -m32mscoff compiler switch.

 It's more than just writing a different object file format, if the goal is to
 link with VC output. It's being ABI compatible with whatever the VC compiler
 puts out.

Is this issue now solved since x64 uses the VC linker?

I wouldn't consider it done until win/32 is also migrated to the visual studio
runtime and linker.  I admit that's an expansion of the original description of
this issue, but I think it's the spirit of it.  And I agree with the spirit.

I'm totally for having support for COFF on win32 too, but IIRC Walter mentioned
win32 will stay with Optlink? (I might be wrong).

You can currently use one other linker on win32 though, Unilink. It often gives
out readable error messages rather than crashing like Optlink.

Walter does not currently plan to make dmd on Windows produce COFF for 32-bit
programs. It's considerably more work to do that on top of the 64-bit stuff,
and he considers 32-bit to be dying out such that it's not worth the effort to
convert it. I doubt that he'd be opposed to someone else doing that work, but
as I understand it, he has no intention of doing it himself.

Speaking for Walter is generally a bad idea.  Anyway, I recall the thread as
64 bit first, 32 bit maybe later.

I'm just repeating what I remember of what he said. I'd obviously have to dig
through the archives to get exact quotes though. And he could certainly change
his mind. Regardless, we're definitely not getting COFF on 32-bit Windows right
now.

This is actually one which I'd really like to see done at some point. The fact
that you have to use dmc to build your C/C++ code is a huge blocker for D on
Windows for anyone who works in an environment which is primarily using
Microsoft or Intel's compiler. It would not be possible for me to use dmc for
C++ where I work, which makes using D there much harder, even if I were to end
up with a project where I would have a chance of choosing to use it in D.

There was a discussion about this on the D list a while back, and it was
suggested that dmd at least be altered such that you could have a plugin
architecture of some kind to swap out linkers. That way, even though dmd would
still use dmc/optlink normally, someone other than Walter could then write and
maintain a plugin which used Microsoft's compiler. So, we could potentially get
support for other linkers without requiring Walter to deal with it.

If someone wants to write the .obj writer for an alternate format, do it.  How
to wire it up with dmd is the least of the problems.

Likely true. But as with many things around here, it requires someone to step
up and do it.
