std::unordered_map (hash table) would be a more direct replacement.
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.
