OK, I give up, what does this mean:
var_of.o: In function `WidthPropagator::WidthPropagator[not-in-charge](unsigned, unsigned)':
/home/denys/Mozart/mozart-gcc3/mozart/platform/emulator/mozart.h:725: undefined reference to `vtable for WidthPropagator'
var_of.o: In function `WidthPropagator::WidthPropagator[in-charge](unsigned, unsigned)':

var_of.o: In function `WidthPropagator::getProfile() const':

collect2: ld returned 1 exit status
the line numbers into mozart.h are inside an indirect base class of
WidthPropagator. This indirect base class has no virtual functions.
I use #pragma interface/implementation. Perhaps I did it wrong, but I
can't see it. Any suggestions?
Cheers,
