  Personally, gcc 2.95 is ancient, especially when dealing with C++ 
code. Even the STL libraries are 100% different code bases. There have 
been many improvements to GCC since then, and it's a major bummer that 
this causes problems for the Haiku team. But unfortunately I think the 
BeOS side of things needs to be fixed so the dependency on an ancient 
and unsupported compiler version isn't a problem anymore.

  I wonder if this is a problem with binary ABIs ? That has changed 
substantially since the GCC 2.95 days. Anyway, I'm curious about why the 
older compiler needs to be used.
