Hi,
right. I should have mentioned it. I added that macro to cxxtools,
tntnet and tntdb so that C++11 is used if available. They do not yet use
any features but using C++11 mode helps the compiler optimizing the
code. I benchmarked it and it really makes the code faster. It do not
affect compatibility to C++03 though.
The marco can be found in the autoconf-archive. You should install that
package on ubuntu. At least under fedora the package is named exactly so.

After pulling code from master branch, I have an error on configure
script. I am using Ubuntu 12.02 with gcc 4.8.1. If I comment
AX_CXX_COMPILE_STDCXX_11 on configure.ac <http://configure.ac> and
regenerate configure, everything works fine.
