The version of GCC implementing the new ABI is going to be
gcc-3.0. I would expect that the symbol "gcc2_compiled." should be
changed to "gcc3_compiled." Do any applications rely upon the symbol
"gcc2_compiled." other than GDB? GDB could detect "gcc3_compiled." to
flag the current use of "gcc2_compiled." and the new C++ ABI.
Let me guess: We are going to need to emit both "gcc2_compiled."
and "gcc3_compiled." for backwards compatibility with GDB instead of
updating the symbol atomically. At least that gives us another "bit" when
"gcc3_compiled." symbols exists and "gcc2_compiled." symbol eventually is
removed (:^).
