If you don't care about non standard-conforming implementations,
then you should use prototypes.  Otherwise, you should use the
__STDC__ predefined macro to select whether to use prototypes or
old-style declarations.  Some clever tricks to assist in this
have been previously posted, but you can do it the obvious way..

#include <stdarg.h>
ret_type func_name( type1 fixed_arg1, typen fixed_argn, ... )
	{ /* stuff using the va_* macros defined by <stdarg.h> */ }
