That's it ! Many thanks. But now comes to me another question. I guess =
that
using RTTI means adding some extra overhead to my app, so I can't use
polymorphic exceptions without losing something in efficiency ? In other
word, it's supposed to work this way or there are plans to fix it in
g++/djgpp ?
