the type name 'data_type', which is specified by the SGI spec as being the correct type name for the mapped type. The second is an overload of insert found in standard containers, taking an iterator as a 'hint' (which we ignore in the standard containers as well). libstdc++'s implementation includes these overloads, and they are needed to make insert_iterator work (which I suspect is the real motivation for including them in the standard containers). The motivation for including these overloads of insert and leaving the mapped_type typedef is to make it easier for clients to migrate to the standard containers. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@136538 91177308-0d34-0410-b5e6-96231b3b80d8
