*rtti.h - prototypes of CRT entry points for run-time type information routines.

*Purpose:
*       RTTI header.
*
*       [Internal]
*
*Revision History:
*       09-26-94  JWM   Module created (prototypes only).
*       10-03-94  JWM   Made all prototypes 'extern "C"'
*       02-14-95  CFW   Clean up Mac merge.
*       03-29-95  CFW   Add error message to internal headers.
*       12-14-95  JWM   Add "#pragma once".
*       02-24-97  GJF   Detab-ed.
*       04-21-00  PML   Add throw(...) exception specifications.
