/***
*typename.cpp - Implementation of type_info.name() for RTTI.
*
*       Copyright (c) 1995-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
*       This module provides an implementation of the class member function
*       type_info.name() for Run-Time Type Information (RTTI).
*
*Revision History:
*       06-19-95  JWM   broken out from typeinfo.cpp for granularity.
*       07-02-95  JWM   now locks around assignment to _m_data.
*       12-18-95  JWM   debug type_info::name() now calls _malloc_crt().
*       09-07-00  PML   Get rid of /lib:libcp directive in obj (vs7#159463)
*       02-19-01  GB    Added Check for return value of malloc
*       07-15-01  PML   Remove all ALPHA, MIPS, and PPC code
