/***
*typeinfo.cpp - Implementation of type_info for RTTI.
*
*	Copyright (c) 1994-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
*	This module provides an implementation of the class type_info
*	for Run-Time Type Information (RTTI).
*
*Revision History:
*	10-04-94  SB	Module created
*	10-07-94  JWM	rewrote
*	10-17-94  BWT	Disable code for PPC.
*	11-23-94  JWM	Strip trailing spaces from type_info.name().
*	02/15/95  JWM   Class type_info no longer _CRTIMP, member functions are exported instead
*       06-02-95  JWM   unDName -> __unDName.
*       06-19-95  JWM   type_info.name() moved to typename.cpp for granularity.
*       07-02-95  JWM   return values from == & != cleaned up, locks added to destructor.
*       09-07-00  PML   Get rid of /lib:libcp directive in obj (vs7#159463)
*
