Case_Sensitive, of course. My bad.

That's unfortunate.

You could submit an ACATS test for Name_Case_Equivalence, which would make 
it more obvious to an implementer when it is missing. (I wrote a couple of 
tests for Ada.Directories a few years back, but Name_Case_Equivalence and 
searching aren't covered. Hierarchical_File_Names is covered.)

Back in the day, AdaCore used to say to say that GNAT followed all RM 
Implementation Advice. It's too bad they don't do that any more (vis-a-vis 
Hierarchical_File_Names, etc.). I had an interesting conversation with 
Robert Dewar on the topic when I built the ACATS test, but the ACATS test 
result is OK as not providing the package is allowed.

I note this is probably the only thing that Ada 2005 thing that Janus/Ada 
does that GNAT does not.
