/*
* This file contains insulation from whether <varargs.h> is being used
* or whether <stdarg.h> is being used. Incompatibilities are hidden behind
* three macros:
* sva_last - last argument in variable arg func defn
* sva_last_decl - declaration for last arg
* sva_start - hides whether nth is used or not
* These macros are non-syntactic (ugh!) but they sure make things prettier.
*
* Do not directly include either <stdarg.h> or <varargs.h> in the code,
* always use this header <ac/stdarg.h> instead.
*
* Never refer directly to va_start, va_arg, or va_dcl directly in the code.
* Direct references to va_list, va_arg and va_end are OK.
