                        ^^^^^^^^^^^ this is "cc":

So it looks like this:

-DCMAKE_C_COMPILER="cc" -DCMAKE_CXX_COMPILER="g++"

(sorry, a c&p mistake)

The testcase is our avogadro package:

mkdir /tmp/test && cd /tmp/test
wget http://downloads.sourceforge.net/avogadro/avogadro-0.2.0.tar.gz
ln -s avogadro-0.2.0.tar.gz avogadro_0.2.0.orig.tar.gz
tar -xzf avogadro-0.2.0.tar.gz
cd avogadro-0.2.0
svn export svn://svn.debian.org/debichem/wnpp/avogadro/debian/

then edit debian/rules and comment/remove the CC and CXX declarations
(they are the workaround for this bug). Then simply run debuild or
whatever you like and you should see, what I see (reproducibly on my
normal system and in pbuilder chroots). I attached the build log to this
mail.

Regards, Daniel
