I, too, encountered the problem of not being able to use virtual functions
in a base class constructor.  The only way I know around this is to either
pass the information in the parameter list, or put the stuff which
uses the virt.func. in a init() member function.  I'm glad this came up
because I posted an article to comp.std.c++ about this and have yet to
receive any feedback.   In the article I asked if it were possible to
implement static virtual functions in C++.  I have found the need for
them several times.  Passing stuff down a class hierarchy is a pain and
it makes it hard to use inheritance when you want to change some parameter
to a base class constructor farther down the line.

I wrote out a scenario where I really needed them in the comp.std.c++ article,
so please check it out.
