WebCore/platform/text/StringBuilder.h already exists.
The Android build is not set up to handle multiple include files with the same name.
Should multiple files with the same name be avoided?
I'm not aware of any other examples of this (other than config.h).
If not, the Android build system will need updating to handle this.
