tried this with -m64 as the value and this is ignored.

More generally, is there a standard rearrangement of files and 
environment variables so that all compilation and linking is 64 
bit, and 32-bit stuff is simply not there?

If you must force dmd to be only 64bit, use sc.ini file to do so and not 
rely on your environment variables.

Also why do you not want 32-bit support?
It's not like it won't work on a 64bit computer, it will.

OK, why?
(This does work, so thank you.)

I've used 32-bit D and DMC a lot on real projects, so I am aware 
of this. I just want to tinker with the installation on a machine 
I use for that sort of thing, without worrying about the 32-bit 
configuration at all, and with no possibility of executing 32-bit 
tools.
