Note that compressed_pair can not be instantiated if either of -the template arguments is an enumerator type, unless there is -compiler support for boost::is_enum, or if boost::is_enum is -specialised for the enumerator type.

Finally, compressed_pair requires compiler support for partial -specialisation of class templates - without that support -compressed_pair behaves just like std::pair.

Finally, a word of caution for Visual C++ 6 users: if either +argument is an empty type, then assigning to that member will +produce memory corruption, unless the empty type has a "do +nothing" assignment operator defined. This is due to a bug +in the way VC6 generates implicit assignment operators.
