When the source does not come with a configure script, which usualy
means debain/rules then runs autoreconf or the like, doesn't it make
sense to also rely on autotools-dev and NOT ship the config.sub/geuss
at all? The choice to ship one but not the other seems to me to be a
bit stupid. Esspecially since config.sub/guess are much easier
replacable.
So yes, please do scan for this. Seems worthwile even without the
legal mubo jumbo.
