  o This kind of stuff is not portable.  Why do you need the ##?  Just
  o remove it, and probably everywhere else it is complained about.  You
  o cannot paste anything with a '('; shame on other preprocessors for not
  o telling you so.

Of course I tried that and the file still fails to
go through g++-2.96 which I got as an RPM
g++-2.96-69.  LEDA is one of the largest legacy
C++ libraries, and its config says it recognizes
g++ 2.95.  So I wonder if I downgrade to 2.95 I
probably will see the light?  Expanding cascading
macros with parameters seemingly needs ('s on the
RHS -- how is it done properly, if at all?

LEDA says it now supports recent KAI and Borland C++.
Is it possible they are all wrong?  Is there a way
to revert to wrong behavior then?  ;-)

I need to start modeling the web as a graph, and
need all the power of C++ and LEDA.  But I'm stuck
for a week with C++ preprocessing standardization,
and enjoy it as an Ada standard lover...
