You can now - 32 bit executables work fine on 64 bit linux!

Maybe I should try it again sometime, but I ran into linker issues when I tried using DMD on 64bit linux. Other than that, DMD worked fine.

Same here, but only on some installations of 64-bit Linux.  Others work fine.  I think the key is that you need the 32-bit version of GCC and all the libraries like libpthread, libgcc, libc, etc. available.  I've been nagging my sysadmin to install these, though it matters less for me now that I have the DMD source and was able to make DMD work on some other Linux boxes that it previously didn't work on for unrelated reasons.  If you have a bunch of Linux boxes around, you can also compile on one that has the 32-bit libs and copy the resulting binary over to one that doesn't, and it will usually work.

On Ubuntu64, which is my main linux dev machine, the following is necessary:

To compile 32 bit programs under ub64:
 sudo apt-get install gcc-multilib libc6-i386 lib6-dev-i386

To run 32 bit programs:
 sudo apt-get install gcc-multilib
 sudo apt-get install g++-multilib

(After long bitter experience, I now keep notes on how to configure the machine after a fresh install <g>.)

When I have free time again I'll give that a try. I found it easier just to put something inside a VM.

Seems I might have to as well.  Before installing these, I was getting a "file not found" error running dmd.  Now everything works perfectly.  Talk about a confusing error message!
