Previous versions of CodeWarrior placed hash_map and hash_multimap in the headers <hashmap.h> and <hashmmap.h> respectively. These headers are still available, but should be used only for transition purposes. They will disappear in a future release. These headers import the contents of <hash_map> into the std namespace (as previous versions o f hash_(multi)map were implemented in std.
#include <hashmap.h> int main() { std::hash_map<int, int> a; }
