On some windows machine the following include line causes error:

berryNativeTabFolder.h

#include "../util/berryAbstractTabFolder.h"

when compiling this file under my machine on MITK-MBI, the include file cannot be found. It is fixed by exchanging this line to:

#include <internal/util/berryAbstractTabFolder.h>

Do not know exactly why, but i will commit this now.
