Which option is the best way to use an unordered_set for an efficient look up, Boost(I guess this is the way to go, since these will be in the next standard) Sgi STL STLPort I am asking because these three are mentioned in Effective STL by Scott Meyers but the book is a bit old.

Unordered associative containers, best choice

If you have to work with a pre-C++11 compiler, use boost:

it's almost everywhere,
it's a header library,
it's modular,
it's compliant with all the standards, so totally compatible with the standard library.
