   There's at least GNAT which fron-end is written in Ada 95,
bootstraped from Ada 83 with incremental use of new features. For
SLOCS, around 200K of documented Ada code, targets, may be more than
20 (GCC back-end plus portability-in-mind helping).

   Something to point out is that Ada 95 has been designed first, then
the compiler follow (idem for Ada 83). It's not the same process than,
for example C++ or ANSI C.

   A priori, the convertion is not too hard for user code (not the
same thing for compilers ;-), an Ada 83 program is likely to be a
legal Ada 95 program (except in a few well known cases).

   So I think that by "convert" you mean "rewrite existing Ada 83 code
to take full advantage of the new features of Ada 95" ;-).
