Hi Gary,
Nope, linking tests fails, but here the error is that it does not find
operators new and delete. Has also to do with libsupc++, for sure. I am
trying to find out where the makefiles must be modified in order to get
libsupc++ added to the list of libraries

Yep, but that was with 2.95.2 ...

Looking further into it
