From d9a55c78e50584b9d1e0c239342b3a432ad59228 Mon Sep 17 00:00:00 2001 From: Scott Duplichan Date: Fri, 10 Apr 2015 03:00:40 +0000 Subject: [PATCH] MdePkg: Fix build fail when DDK3790 tool chain is used Modify the preprocessor check for variadic macro support. The existing check assumes all Microsoft compilers with major version of 14 and greater support variadic macros. This is almost correct. An exception is the X64 compiler from DDK3790. This compiler has version 14.00.40310.41, yet does not support variadic macros. Both VS2005 compilers have version number 14.00.50727.762 and do support variadic macros. For simplicity, this change suppresses the use of variadic macros for all Microsoft compilers with version 14 or smaller. If the variadic macro support needs to be restored for VS2005, that could be done using new logic invloving _MSC_FULL_VER.
