Hello,
that is the runtime type information of egcs. To get g++ compatible
libraries, you need the compile option -fno-rtti and maybe
-fno-exceptions.
Have you thought about rebuilding the ROOT rtti on top of the standard
C++ rtti or do you use other features of the compiler, which is
already much closer to the standard than gcc 2.7?
