See gold/system.h -- for C++03 compilers, gold uses unordered_map (and unordered_set) from std::tr1 if available, otherwise falls back to std::map (balanced binary tree, usually red/black), with even older compilers. The idea being that you'll be able to use gold with older compilers, though it'll run slower. Thanks, Pedro Alves
