Compilation fails with -static on MacOS X due to qtmacextras

There is some duplicate code in:
qtbase/src/plugins/platforms/cocoa/qmacmime.h (and corresponding .mm)
qtmacextras/include/QtMacExtras/qmacpasteboardmime.h (and corresponding .mm)
Source code contains this comment:
qmacmime.h: // Duplicate of QMacPasteboardMime in QtMacExtras. Keep in sync!
qmacpasteboardmime.h: // Duplicate of QMacPasteboardMime in the Cocoa Platform Plugin. Keep in sync!

Such hack is not compatible with a static build (build fails).

if I trash all code except:
"void qRegisterDraggedTypes(const QStringList &types)"
in qmacpasteboardmime.mm, build is OK (but because I don't the reason there is duplicate code and because I don't use QMacPasteboardMime, I don't know if such patch is OK for everybody).

Using qt-everywhere-opensource-src-5.2.0-rc1.* source package.
with this config:
./configure -release -opensource -confirm-license -static -no-framework
make

After some time, I have this error:
