config.log from failed build
Recent trunk at r262520 failed to build on, it was configured with
$ CC=/usr/bin/gcc CXX=/usr/bin/g++ ../trunk/configure --prefix=$HOME
--enable-languages=c,c++,fortran --enable-maintainer-mode
for x86_64-pc-linux-gnu and then built with
$ make -j8
which led to the errors
