For the record, gcc 4.4, let alone 4.8, do provide unique_ptr. I've been 
using unique_ptr for a few years now (since circa 2011-2012, I think). 
I've been using gcc 4.4 in our production projects in C++0x mode for a 
few years until we upgraded to 4.7. Yes, 4.4 is buggy in many ways, but 
it still supports the fundamental C++11 features, including rvalue 
references (early version of) and unique_ptr. IMO it is fair to say that 
most currently wide spread C++ compilers do support C++11 to some degree.

MS and C is a whole different story. MSVC never supported C properly, 
and I don't think it ever will. They do try to support C++ better, at 
least feature-wise, at least in parts that are not C.
