GNAT Normalize_Pathname version differences

GNAT Normalize_Pathname version differences

(Posting this here for archive purposes to aid future Google Group 
searches :-)

Somewhere between Gnat 3.15p and Gnat GPL 2005, the behavior of the 
Normalize_Pathname function in Gnat.Directory_Operations changed.

The 3.15p version appended a '/' if the pathname was that of a 
directory, at least in the Linux version, the GPL 2005 version does not. 
  I can't say what it does on Windows, but I would expect the same 
behavior, with the corresponding directory separator.

I diffed the sources of Directory_Operations for the two versions, and 
saw there are significant differences between the Normalize_Pathname 
implementations, as well as other things.

Might it be because they are using GNAT.Directory_Operations to 
implement Ada.Directories?

I didn't look in detail, but Normalize_Pathname changed significantly, 
much more than would be attributable to just swapping directory 
management packages.  I expect one could browse the CVS tree if they 
were really interested in how it evolved.
