From 14d16872298a88ddbf704ccdd5b0fc3b0e78778b Mon Sep 17 00:00:00 2001 From: Sinclair Yeh Date: Thu, 4 Aug 2016 12:57:06 -0700 Subject: svga: Limit svga message capability to newer compilers The assembly code used by the SVGA message feature doesn't build properly with older compilers, so limit it to only gcc 5.3.0 and newer. Also modified the stubs to avoid "unused variable" warnings.
