--- Comment #1 from Walter Bright <bugzilla@digitalmars.com> ---
__va_argsave is an internal symbol with more or less magic semantics. Support for it has been removed, as proper stdarg semantics now works. Use core.stdc.stdarg, and va_list, va_start, va_arg and va_end.

It's documented for D1 [1], under "C-style Variadic Functions". I still think it's a regressions, this code originated from D1.
