From e9c527163d31da9f616e989a90429729525c5233 Mon Sep 17 00:00:00 2001 From: Paolo 'Blaisorblade' Giarrusso Date: Sun, 1 May 2005 08:58:54 -0700 Subject: [PATCH] [PATCH] uml: move va_copy conditional def GCC 2.95 uses __va_copy instead of va_copy. Handle it inside compiler.h instead of in a casual file, and avoid the risk that this breaks with a newer compiler (which it could do).
