[Qt-creator] Precompiled headers

[Robert Caldecott]

OK, this isn't strictly a Qt Creator issue but I thought it would be
the best place to ask.  I see that qmake supports a PRECOMPILED_HEADER
command but I'm unsure if this will work with the MinGW tools that
ship with Qt Creator?  Does anyone know for sure?  If it isn't
supported then does anyone know if the new version of MinGW (that uses
gcc 4.4 and will *possibly* ship with Qt 4.6) will support pch?
