Hi,

I have a test that should compile the code with C++11 options. For eg. 
GCC, I have a rule like this, which I do not like

<toolset>gcc-4.4:<cxxflags>-std=c++0x
<toolset>gcc-4.5:<cxxflags>-std=c++0x
<toolset>gcc-4.6:<cxxflags>-std=c++0x
<toolset>gcc-4.7:<cxxflags>-std=c++11

I would like to know:
- if there is a better way to do this
- if it is possible to set the option "-std=c++11" for compilers with 
versions >= 4.7

Thanks,
Raffi
