Re: Multilib support?
Thanks for the answer!
Yeah, building is where the issue is. gnat-8 and gnat-8:i386 conflict with each other, and there doesn't seem to be a libgnat8-dev package available at all. It's a good thing running isn't an issue - it's a nightmare on the various RHEL variants - but compiling
both 64 and 32 bit applications is our main goal at the moment. As far as I can tell, it's not the compiler itself that's the issue, but rather a lack of a separate non-conflicting package containing the 32-bit RTS.
I'm not totally familiar with packaging for Debian, and especially in this area. I'd happily try to contribute with this, since it's a pretty strong need for us at work.

Most usages of 'multilib' are now covered by 'multiarch'.
All multiarch variants of Ada library packages (providing the shared
object) are coinstallable (in your case i386 and amd64), so you will
should no problem *running* an i386 program on an amd64 system.
As far as I know, the same holds for gnat-8 and libgnat8-dev, but most
other -dev packages are not coinstallable yet, so you will probably
need a chroot or something similar to *build* an i386 program.
