Correct. Not shared.

I got GNAT to work by: 
- booting into Win XP 
- exporting the ACT registry settings (which contained references to C:)
- saving the reg-file
- booting into Win 2003
- importing the reg-file into 2003 registry (on E:)
- inserting C:\GNAT ... at the beginning of the path variable

I was then just curious whether my manual changes to the environment
were similar to what you get when you install GNAT in another directory
than the default (C:\GNAT...).

Case closed, thanks to all.
