Message <Context> stdarg.h macros might be required if the address of the parameter <name> is used to index through a parameter list. Description Some older C programs will traverse a function's parameter list by taking the address of one of the parameters and then adjusting it to get to subsequent parameters. In most cases, this technique will not produce the desired results on Alpha. This message is specific to UNIX, and is only output if -varargs option is specified. User Action If the address is used to walk the parameter list, recode the function to use the standard stdarg.h macros.
