modification history
--------------------
01s,16nov12,xwu  fixed WIND00388613  the coverity issue of RPC
01r,29apr10,pad  Moved extern C statement after include statements.
01q,25jan10,y_t    update for LP64
01p,16nov01,spm  fixed modification history: version 01o created
01o,25oct01,rae  added build macro to support different Tornado versions
01n,16nov98,mak  changes due to moving pRPCModList from the TCB to the LCB
01m,22sep92,rrr  added support for c++
01l,26may92,rrr  the tree shuffle
		  -changed includes to have absolute path from h/
01k,04oct91,rrr  passed through the ansification filter
		  -changed includes to have absolute path from h/
		  -changed copyright notice
01j,01may91,elh	 added references to filename<Include>.
01i,05oct90,shl  added copyright notice.
                 made #endif ANSI style.
01h,02oct90,hjb  defined RPC_ERRBUF_SIZE, added clnt_rawExit, svc_rawExit
		   and errBuf to struct rpcModList.
01g,15may90,dnw  moved rpc static structures from various rpc modules to
		   the structure defined here.  This simplifies the
		   initializations and requires fewer mallocs.
		 renamed the structure type from MODULE_LIST to RPC_STATICS
		 renamed the macro for pointer in the tcb from taskModuleList to
		   taskRpcStatics
		 added rpc_createerr macro
01f,15apr90,jcf  made taskModuleList a macro thru taskIdCurrent.
01e,30oct89,hjb  added bindresvport in MODULE_LIST
01d,20may88,ak   made 01c version be rcs'd as part of yuba migration
01c,19apr88,llk  added nfsClientCache to MODULE_LIST.
01b,05nov87,dnw  moved definition of taskModuleList to rpcLib.c.
