OK, the code generation appears to work with the latest SIP snapshot and
PyQtMobility 1.0, building against Qt Mobility 1.1.1. However, I encounter
the following error when building the QtLocation module:

Previously, I've worked around this by "fixing" the qgeorouterequest.h
header file, but one of the Qt Mobility developers suggested that the failure
wasn't a Qt Mobility issue.
