stack-1.C is failing as there is stack overflow in the gimplifier, there
is a PR for this report and I thought it was xfailed. RTH is working on getting
this one fix by pulling some of the GENERICIFIER into the C++ front-end.

gcov-1.C is failing for mainly because the profiling stuff is not working right
on the mainline  after tree-ssa was merged in, Jan is working on this.

warn7.C looks to be a problem when to warn about a problem when a function is
cloned, I do not know when this started happen.
