For several reasons my experiment is actually bound to Debian Woody, which uses gcc 2.95 and libstdc++ 2.1. Unfortunatelly this very old version of stdc++ libs does not comprises the vector<>::at(int) method (which is used at least in G__Base2.cxx:21580).
For this reason I can not compile newer root version on my system. I will do a patch and send you if you think you will commit it.
Hi,
You will need to appropriately patch cint/lib/prec_stl/vector.
If you send a tested patch, we will upload it.
Cheers,
Philippe.
