+modification history
+--------------------
+01g,28apr10,cww  LP64 adaptation
+01f,30oct09,gls  modified build warning when ND spinlocks used when 
+                 DETERMINISTIC VSB used (WIND00188965)
+01e,24jul09,kk   add warning on the use of ND spinlocks
+01d,07nov08,kk   added SPIN_LOCK_ISR_ND_DECL() macro
+01c,21oct08,kk   added spinLockIsrNdXXX() prototypes
+01b,16jan08,dlk  Renamve as spinlockIsrNdLib.h. Move function
+                 prototypes to private/spinlockIsrNdLibP.h for now.
