From 490409a57be4916d587dea33761cbd801efd8dc7 Mon Sep 17 00:00:00 2001 From: Bill Currie Date: Mon, 28 Aug 2000 20:21:28 +0000 Subject: [PATCH] Well, that's sgl going. It seems to have some issuesi. Gun and sbar were white, and it crashed my box on exit, but that's most likey the X server (i810, glx does the same). --- configure.in | 2 +- source/vid_sgl.c | 712 +++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 713 insertions(+), 1 deletion(-) create mode 100644 source/vid_sgl.c diff --git a/configure.in b/configure.in index 2c5498f..b3a8ee2 100644 --- a/configure.in +++ b/configure.in @@ -951,7 +951,7 @@ if test "x$HAVE_SDL" = xyes;
