What's the version of your clang? I am using MacPorts Clang 3.1 and 
never have this error.

In fact, I just rebuilt Qt 5 from latest git and other than 
qbasicatomic.h (which should be fixed with clang 3.2) and 
qmacstyle_mac.mm (CGFloat size is different in 32-bit), I don't have any 
error to deal with. Although I don't build webkit.

This is my configure line if it helps:
./configure -developer-build -opensource -confirm-license -nomake 
examples -nomake tests -c++11 -platform macx-clang-libc++-32
