Cannot build QT-everywhere-opensource for Windows CE 6 / MSVC 2005 / STLPort 5.2.1

QT everywhere 4.6.0 cannot be built out-of-the-box with STLPort.
Here's the error message from the compiler:

qfuture.cpp
qfutureinterface.cpp
concurrent\qfutureinterface.cpp(500) : error C2332: 'struct' : missing tag name
concurrent\qfutureinterface.cpp(500) : error C2011: '<unnamed-tag>' : 'enum' type redefinition
concurrent\qfutureinterface.cpp(56) : see declaration of '<unnamed-tag>'

This happens because
basetyps.h and objbase.h in Windows CE 0x502 SDK define 'interface' as 'struct'. Just use another name for the variables.
