Re: Building the Ada compiler... is http://gcc.gnu.org/install/build.html correct?

It appears that we were too optimistic about providing binaries, and
that this requires too much work/set up on our side.
     
If this is still felt as a necessity, we would be glad to host the
binaries contributed by other people on the libre site, although I
guess this could also be done on the gcc.gnu.org site directly (whichever
way is more convenient).

Given that there have been a couple of releases with Ada included, and
that more people have a pre-existing Ada set up, this issue may not be 
as important as it used to be.

The Ada front-end is not at a stage where binary compatibility can be ensured
for lots of various reasons, so I think the above concern is premature.
Also, the provided binaries will only be provided to help
people bootstrap gnat, they do not have to be binary compatible to
build gnat properly.

You simply need to set the environment variable GNAT_ROOT to <somedir>/usr/local
