If Yacc-compatibility is really important, then you could try Ayacc and
Alex but I do not know whether they support Ada 95. They are on many of
the CDs posted with the journal "Ada Letters", which ESA subscribes to.

If instead a "reasonable" tool would really be top-down then you could try
the Ada 9X grammar for the Java Compiler Compiler which does not support
fixed types. The grammar is at
HTTP://WWW.Cobase.CS.UCLA.edu/pub/javacc/ada9x.jj and recent versions of
JavaCC are at HTTPS://JavaCC.dev.Java.net/
