Talk about a "professional" distribution :)

I don't know what Ubuntu changed to gcc-defaults but, in Debian, in
gcc-defaults version 1.64 I made gnat-4.3 the default on all
architectures; version 1.66 reverted to gnat-4.2 on alpha, mips and
mipsel without consulting with me, and 1.70 finally reverted that,
thereby completing the transition to gnat-4.3 as the default on all
architectures.

I never intended gnat-4.2 to be the default on any architecture and
Ubuntu diverges from Debian and risks breaking package dependencies.
So, at this point, I am forced to recommend against Ubuntu 8.04 for
Ada development.  Previous versions are OK since they follow the
policy for all Ada packages.  If you want a stable Ada development
platform, get Debian stable, which has "long term support" built in.
