Arch Linux

Quite a few of the gnat sub-commands appear to be missing. Checking this I see the following:

% ls -l $(gnat --help | awk '/gnat/ { print "/usr/bin/"$3 }')
ls: cannot access '/usr/bin/gnatcheck': No such file or directory
ls: cannot access '/usr/bin/gnatelim': No such file or directory

I'm not really sure why they are missing, oversight or are they simply not included?
