From 261c0028dcc3d15f82ed7f5db6cb89fc77083418 Mon Sep 17 00:00:00 2001
From: Richard Sharpe <sharpe@samba.org>
Date: Fri, 24 Oct 2003 05:47:39 +0000
Subject: [PATCH] Check for va_copy before you check for __va_copy, since
 va_copy is the actual standard, and __va_copy was the proposed standard.
 (This used to be commit 4ab7947e601e61cacd7ff541ee881850d9808387)
