Hi,

All this Ceph stuff finally used to compile under FreeBSD.
And all testss completed correctly.

But somewhere in the Ceph-tree there was a lot of template and trait
code added/replaced.
Problem is that this compiles under GCC, but Clang throws an error. It
looks like it cannot select types of automagic conversion.

But this template/trait stuff is too much for me to wrap my head around.
I'm reading up a lot, but that does not yet get me anywhere.

So I was wondering if anybody with more C++ knowledge would like to
assist and give some clues as to how to fix this.

The error report is at:

http://cephdev.digiware.nl:8180/jenkins/job/ceph-freebsd/39/consoleFull

And the ceph code can be found at:
https://github.com/ceph/ceph
