Fingers crossed!

Argh, this looks like a (silly) problem with libatomic-ops-dev.  We should 
have a configure/build option to use the new c++11 atomic types instead; 
that may be less painful than dealing with it.

Barring any last-minute catastrophies, 0.48 should be released Monday.  
Packaging-wise it will be pretty similar to 0.47.2, except for the stuff 
from you I've pulled upstream over the last couple of weeks (separate 
ceph-fs-common package, small fixups).  0.48 will also be our first 
longer-term stable release, so it is much better-suited than 0.4.2 for 
inclusion in wheezy.
