True as well. Both lines lead to the same result (on the 1-8-branch), so 
any of the two could be removed with the same effect (probably rather 
the latter).

Nevertheless this whole autogen.sh file is IMHO quite a mess. Personally 
I would now prefer a much simplified version, e.g. like this one
http://cvs.sourceforge.net/viewcvs.py/ktoblzcheck/ktoblzcheck/autogen.sh?rev=1.5&view=markup
(happens to be committed by myself) and if any of these commands cannot 
be found (which are all visible due to the -x argument), then leave it 
up to the developer to set a correct PATH. Our long autogen.sh script 
eventually doesn't do anything else than what this very short script 
does. In any case we won't change the 1-8-branch anymore, but we might 
consider something along these lines for the gnome2 branch.
