Ada95 compiler using Ada83 as back-end

[Gautier <gautier.demontmollin@maths.unine.ch>]

... does it exist ?

What I mean: a program that translates Ada 95 code into
"intermediate" Ada 83 code, referencing some packages
like Interfaces, implementation of streams etc., eventually
system-dependant.

Just curious...

[Some people (at least 1 in c.l.a.) will ask: but why would
you want to look for such a beast ? My answer: there are
very good Ada 83 compilers, that may have been replaced by
other Ada 95 compilers not based on their predecessors, maybe
not as efficient on some points - e.g. optimised numerics,
arrays etc. It would be useful to compare evolution of some
features and maybe help tuning new Ada 95 compiler versions.
Of course one can compile Ada 83 programs
on both 83 and 95 compilers, first. But it could be interesting
to compile Ada 95 with these old compilers for special needs]
