+--------------------
+01i,21may10,elp  64bits support.
+01h,19jun07,elp  added access violation type macros.
+01g,08nov06,elp  can be included in assembly file
+01f,10mar04,dbt  Fixed _WRS_IS_SUP_EXC() macro.
+01e,09feb04,jmp  added _WRS_IS_SUPV_EXC() macro.
+01d,21oct03,jmp  replaced padding field of EXC_INFO by access type.
+01c,28mar03,jmp  added exception numbers.
+		 replaced INSTR by UCHAR to use this file from host side.
+01b,30may00,elp  renamed errCode in accessAddr.
+01a,29apr98,cym  written based x86 version.
