Bero i got lot of error when building Qt 5.8.0 on 3.0 tree:

/usr/bin/../lib64/gcc/x86_64-mandriva-linux-gnu/5.4.1/../../../../include/c++/5.4.1/bits/c++0x_warning.h:32:2:
error: This file requires compiler and library support for the ISO C++
2011 standard. This support must be enabled with the -std=c++11 or
-std=gnu++11 compiler options.
#error This file requires compiler and library support \

/usr/include/qt5/QtCore/qbasicatomic.h:61:4: error: "Qt requires C++11 support"
#  error "Qt requires C++11 support"
   ^

See for example https://abf.openmandriva.org/build_lists/95960

Should i add  -std=c++11 in optflags ?
