-* This function is available for iX86 only.
-*
-* When VC++ generates debug code, it stores the value of the stack pointer
-* before calling any external function, and checks the value following
-* the call. It then calls this function, which will trap if the values are
-* not the same. Usually this means that the prototype used to call
-* the function is incorrect. It can also mean that the .spec entry has
-* the wrong calling convention or parameters.
