36 Description: Created separate header file for shl function.
38 Description: Changed prototype of the mult() function. Instead of using global
39 a pointer to overflow flag is now passed into the function.
41 Description: Updated template. Changed the parameter name from "overflow" to
42 "pOverflow" in the function prototype declaration
44 Description: Moved _cplusplus #ifdef after Include section.
