Hi,

I've the following setup(s):

 - GNAT 3.15p at Sarge (Debian 3.1) and at Windows 2000 Professional.
 
 - I'm using Martin Dowies Ada95 port of Ada.Containers (which can be
   found here: http://www.martin.dowie.btinternet.co.uk).

   I didn't want to install Ada.Containers as precompiled packages
   (*.ali- and *.o-Files I mean) since I found some minor buglets in
   the code and want to correct them when I find them.

   Instead I use -I... as switch to gnatmake to point gnat make to the
   source distribution.

 - Of course then Ada.Containers doesn't recompile because its in the
   Ada.* package hierarchy and therefore considered 'internal' by Gnat.

   I therefore also give the switch -a to Gnat, which according to
   gnat_ug should incite gnatmake to

   "Consider all files in the make process, even the GNAT internal
    system files".

   As I understood that, gnatmake should only remake the internal
   packages in this situation if the corresponding *.ali- and
   *.o-Files are not up to date.

Actually that is not what happens: Under Debian it works as I
expected, but under Windows a lot of internal packages are recompiled
to project-local *.ali and *.o files. It is almost as if gnatmake
can't see the packages in .../lib/adalib/.

All installed files in .../lib/adalib/ are (as far as I can see) much
younger then the sources in .../lib/adainclude/. So that doesn't seem
to be the reason why things go wrong.

Does anybody here have an idea what I'm missing?
