The ellipsis is part of the function prototype, and so is removed by the
deprotoizer:
	int printf(char const *fmt, ...) {  /* as stored in source file */
	int printf(fmt) char *fmt; {        /* after deproto and -Dconst="" */
which is acceptable to the Classic C compiler.  <stdarg.h> says
	#define va_start(ap, parmN) (ap = (char *)&parmN + sizeof(parmN))
in the typical implementation.
