Which part of a Qt build? The build of:
 - qmake
 - a host library or of libQtBootstrap.a
 - a target library

Also, since you're on OS X, why does the build think you're cross-compiling? 
Did you pass different -platform and -xplatform switches? Or am I mis-
interpreting the situation?

It's valid C++11, though it's not valid C++98.
