Summary0005752: --cxx11 configuration flag broken for GCC<4.7
DescriptionWhen using --cxx11 on configuration I get:

Checking for compiler flags ['-std=c++11'] : no
The configuration failed

From GCC documentation [1]:

To enable C++0x support, add the command-line parameter -std=c++0x to your g++ command line. Or, to enable GNU extensions in addition to C++0x extensions, add -std=gnu++0x to your g++ command line. [b]GCC 4.7 and later support -std=c++11 and -std=gnu++11 as well[/b].


Additional InformationI (unclearly :)) reported it when describing unrelated bug 0005751.
TagsNo tags attached.


related to 0005751 closedx42 flag for c++11 is not -std=c++11 but -std=c++0x here (linux, gcc 4.6.4)
