Hi,

I would like to submit a patch for shared_ptr, to make it compatible  
with root/cint.  cint is a C++ interpreter used by the root  
framework, which is popular in high energy physics.  Details can be  
found at http://root.cern.ch/twiki/bin/view/ROOT/CINT.

The patch uses one of the alternative "operator bool" definitions  
already in place when running with root/cint.

Thanks in advance,
Nils
