--------------------
02h,19mar02,sn   SPR 71699 - decouple from cplusUsr.o; general clean up
02g,06nov01,sn   include <exception> rather than prototyping set_terminate
                 (fixed Diab build failure)
02f,11oct00,sn   break out INCLUDE_CPLUS_LIBGCC as a seperate (but required!) 
                 component
02e,11oct98,ms   reworked 02d fix, since it was causing bootrom builds to fail
02d,08oct98,sn   moved defn of cplusXtorStrategy from cplusUsr.cpp to here
02c,17sep98,ms   removed force-links of loader support modules
02b,16jan98,sn   add force-link of 'new-style' new/delete
02a,15jan98,sn   add force-link of exception handling/RTTI
01f,20jun95,srh  remove force-link of iostreams.
01e,18jun95,srh  change cplusCfront to cplusCore.
01d,18jun93,jdi  more doc cleanup.
01c,03jun93,srh  doc cleanup
01b,23apr93,srh  implemented new force-link/initialization scheme
01a,23apr93,srh  written.

DESCRIPTION
This module defines cplusLibInit, and implements a scheme that forces
most of the WindC++ run-time support to be linked with VxWorks.
Initialization is actually performed by cplusLibMinInit(), which is
defined elsewhere.
