Run <code>./configure --enable-c++11 --enable-test-cpp11</code>.
Run <code>./configure --enable-c++11 --enable-test-c++11</code>.


This option enables the inclusion of file <code>base/test_new_standards.cpp</code> where we have tests for the desired important C++11 standard features (thanks to ZvikaZ).

(1) --enable-c++11 breaks compilation in base/commandLine.cpp
==Notes==
 
<references />
(2) --enable-c++11 breaks compilation in backends/fs/posix/posix-iostream.cpp with error 'fileno' was not declared in this scope. C++11 support is enabled by default, though, so the flag is not needed.
 
(3) --enable-c++11 breaks compilation in backends/platform/psp/default_display_client.cpp with error 'bzero' was not declared in this scope. C++11 support is not enabled by default, so cannot test the support, because compiler fails in default_display_client.cpp earlier.
