I had answers from gnu c++ newsgroup. It seems that both 
-fhandle-exceptions and -frtti flags are needed. it is in gnu g++
faq. I have tried, and then many strange symbols weren't defined
at linking stage :-( I'll look to that more precisely tonight.

Yes, of course, but I really would like to use exceptions handling, as
it is very convenient for a full-C++ program.
