Thiago you work to qt5 which include the c++11 stuff, so probably you 
know better than rumors around, must admit that I've spoken by those 
rather than an extended experience in the field.

What made me think the rumors were true is:
a) many programs which support to be compiled with c++11 syntax require 
gcc-4.7
b) that the resolved/fixed bug list is rather long:

A search for resolved/fixed bugs with 'C++0x' or 'C++11' in the summary
580 bugs found [1]

the same search with gcc-4.7.{0,1,2} as "known to fail" is much shorter:
22 bugs found [2]

feature wise instead the increment in 4.7 seem to be short (there was a 
diff in the first mail):

Non-static data member
New wording for C++11 lambdas
Template aliases
Delegating constructors
User-defined literals
Extended friend declarations
Explicit virtual overrides
