   My point was that in this case not only does ppl-0.11 require
the existing soversion of cloog to be rebuilt but also all other
previously built gcc releases that used it as well.
   Considering that the existing cloog-0.15.9 sources refuse
to build against ppl-0.11 due to the version check, it presents
an opportunity to do a soversion bump and a cloog-0.16 release
which would require ppl-0.11 as the minimum required ppl. I do
understand that this isn't the conventional reason to do a
soversion bump, but it does have the advantage of solving the
coherency problems in gcc/cloog/ppl builds.
