this means v3 is NOT the default since without this configure settings
gcc use v2! or am I wrong ?
or what the "Eventually." mean ?

so I don't have to use the --enable-new-gxx-abi ?
or it's better if I use it ?

so the real question (although the above also important:-):
if I would like to compile gcc vith v3 support and would like to get a
working gcc, g++ and stdc++ do I use --enable-new-gxx-abi ?
since jakub's gcc-new-abi.patch contained (it's a bit outdated, but you can
find it) some stuff which is not in the current cvs, so what is the truth?:
