[Cbc] Cbc-2.9.7 doesn't compile with gcc-5

[ycollette.nospam at free.fr]

Hello,

I downloaded Cbc-2.9.7 to compile it on fedora 23 64 bits.
I wanted to compiled Cbc with aboca enabled.
Here is my command line:

./configure --prefix=/opt/cbc-2.9.7 --enable-aboca=4 

And some of the errors I've got:

then mv -f ".deps/ClpCholeskyDense.Tpo" ".deps/ClpCholeskyDense.Plo"; else rm -f ".deps/ClpCholeskyDense.Tpo"; exit 1; fi

Next, I configured cbc with the following command line:

./configure --prefix=/opt/cbc-2.9.7 --enable-aboca=4 CXXFLAGS=-fcilkplus

And now, I meet the following error message:
