*Purpose:
*       Defines C++ new() routines.
*
*Revision History:
*       01-12-95  CFW   Initial version.
*       01-19-95  CFW   Need oscalls.h to get DebugBreak definition.
*       01-20-95  CFW   Change unsigned chars to chars.
*       01-23-95  CFW   Delete must check for NULL.
*       02-10-95  CFW   _MAC_ -> _MAC.
*       03-16-95  CFW   delete() only for normal, ignore blocks.
*       03-21-95  CFW   Add _delete_crt, _delete_client.
*       03-21-95  CFW   Remove _delete_crt, _delete_client.
*       06-27-95  CFW   Add win32s support for debug libs.
*       12-28-95  JWM   Split off delete() for granularity.
*       05-22-98  JWM   Support for KFrei's RTC work, and operator new[].
*       07-28-98  JWM   RTC update.
*       01-05-99  GJF   Changes for 64-bit size_t.
*       05-26-99  KBF   Updated RTC_Allocate_hook params
