There will be the same problem WRT C++ when upgrading from 3.4 to 4.0 either way. Both "g++-2.95.2 -fno-vtable-thunks" and "g++-2.95.2 -fvtable-thunks" are incompatible C++ platforms from G++ 2.7.x. People wishing to use C++ programs compiled on FreeBSD 3.x need to install the ``compat3x'' distribution to get the libstdc++.so.? compatibility library. For ports those same people will have to keep their 3.x compiled C++ libs (in /usr/local/lib & /usr/X11R6/lib) around how ever they like. Again, this requirement would be the same with or w/o the C++ ABI change I just made. -- -- David (obrien@NUXI.com) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
