-* NOTES
-*  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.
