The consensus in comp.lang.ada from the _many_ times this has been
addressed in the past is that no general purpose translator could
be built since the semantics of Ada are a superset of the semantics
of C or C++ (no tasking for example).  Please read archives of the
comp.lang.ada rather than starting the discussion up from scratch.

I don't know of any, but sometimes such reports are confused due
to the fact that Ada compilers and C compilers use a common back
end.  Examples are GNAT and DEC Ada.  In each case the back end
has to include at least some Ada-specific features, which some
might views as "proof by example" that a general purpose Ada-to-C
translator is not possible.
