/*
**  SYSERR -- SYStem ERRor message print and abort
**
**	Syserr acts like a printf with up to five arguments.
**
**	If the first argument to syserr is not zero,
**	the message "SYSERR:" is prepended.
**
**	If the extern variable `IIproc_name' is assigned to a
**	string, that string is prepended to the message.
**
**	All arguments must be null-terminated.
**
**	The function pointed to by `Exitfn' is then called.
**	It is initialized to be `exit'.
