Yeah, Ada uses a special setup where some debug info is expressed via
magic symbol names.  The Ada compiler is moving away from this --
gcc recently switched its default to "minimal encodings", but even with
this in place there are still some things that require this treatment.

Unless there's some strong need, my inclination would be to not do anything
special to support older versions of the compiler.  We're trying to move
everything to "real DWARF", at least to the extent that this is possible.

Joel is away right now, but I'll CC him to see what he thinks.
