Thanks.

That's not the question.
That's the second time someone tries to just "moc and include" a header file.
I think it's time to add this feature to qt(4).jam.
I've experimented with copying and modifying the "moc and include cpp" 
extension but missed types/qt.jam :-((( so I got stuck.
The rationale for this is that Qt(4) itself uses "moc and include" extensively 
so we must support this if we want to compile Qt4 with BBv2 someday ;-))

Btw: right now, the [ cast _ MOCCABLE_CPP ] hack works, but in the long run 
I'd prefer a cleaner solution which copies qmake's behaviour of automagically 
determining which files to moc and which generated files to compile or not to 
compile.
For a rationale take a look at my attemps at compiling Qt4 with bjam I posted 
some weeks ago :-)) The Jamfiles simply start to look ugly ;-)

Yours,

Jürgen
