Hi, A recent patch to clang enables a warning for any use of the register storage class specifier when -std=c++11 is used.
$ ~/dev/build/qtbase/llvm/bin/clang++ -std=c++11 -fPIE -
I$HOME/dev/prefix/qtbase/include -c
~/dev/src/qtbase/src/corelib/tools/qstring.h
clang-3.4: warning: treating 'c-header' input as 'c++-header' when in C++
mode, this behavior is deprecated

This will be quite noisy for Qt and for users of Qt. Should we remove the use
of register from Qt? Or replace it with Q_REGISTER which is empty for c++11?
Thanks,
