I tried it an it came out there are other C++11 stuff in the code. I tried
to replace them, but the compiler does not help me with finding C++11 code.
When I compile with --std=c++03 flag, compiler just write out:
error: #error This file requires compiler and library support for the ISO
C++ 2011 standard. This support is currently experimental, and must be
enabled with the -std=c++11 or -std=gnu++11 compiler options.
Is there any option to avoid this general error and force the compiler to
try the older standard.

Thanks,
Tamás
