Please find a new patch for qt4.jam attached (qt4.jam.diff).
It enables passing <include> and <define> to the moc.

Right, the environment is attached.
unbzip2/tar in $QTDIR and call bjam on it ;-))

Caveats:
- requires .moc files from qmake build for inclusion by the corresponding .cpp 
file. _every_ sub-Jamfile adds the needed <include> for release, debug and my 
special develop (release, debug-symbols without NDEBUG) variant.
- does not build tools (moc, rcc, uic, uic3)
- Works only on linux (debian amd64 unstable, SuSE-9.2)

Especially platform specific things like freetype, the free sql engines and 
more are currently hardcoded into the Jamfiles. Those are normally detected 
by configure but we need a way to configure them automagically or manually in 
user-config.jam. 

I've done no "magical" things sofar, just a quick hack to see whether it work 
in principle.

Comments welcome, but I'll be away from mail tomorrow, so don't worry ;-)

Yours,

Jürgen
